Abstract

Kidney failure is a kidney function disorder that occurs in more than 90.00% of people in the world, especially in developing countries. In 2013, around 12.50% of the 25 million population experienced kidney failure and 78.00% had to undergo dialysis for life. In this research, a hemodialysis method was developed, namely molecularly imprinted membrane (MIM), which has high selectivity for urea molecules with high binding capacity using a membrane in the form of hollow fiber. Variations in research use urea transport concentrations such as 50, 200, and 300 ppm. The analysis using UV-vis spectrophotometry on HFHIM with a solution mixture of 50 ppm showed that the receiving phase by the membrane was 70.48% urea, 12.97% creatinine, and 9.42% vitamin B12. Meanwhile, the feed phase is 28.25% urea, 85.41% creatinine and 88.64% vitamin B12. When using HFHNIM, the receiving phase is urea 44.78%, creatinine 58.51%, and vitamin B12 31.00%. Meanwhile, the feed phase is 54.55% urea, 40.57% creatinine, 68.29% vitamin B12. The selectivity of HFHIM for urea is better than creatinine and vitamin B12 compared to HFHNIM, in the order of selectivity urea > creatinine > vitamin B12.

Abstract

Chronic kidney failure is a disease that affects the world's population and an alternative solution is hemodialysis. Hemodialysis is the process of cleaning the blood from urea and creatinine through a semi-permeable membrane in the form of a hollow fiber membrane (HFM) with the following advantages: flexible and low energy requirements. The weaknesses of commercial hemodialysis membranes are that they are hydrophobic, chemical resistant, and low biocompatibility. This research uses a membrane of polysulfone combined with eugenol and polyethylene glycol (PEG) or polyethylene glycol diglycidyl ether (PEGDE). Eugenol has allyl, hydroxy, and methoxy groups which are derived from polyeugenol via allyl groups and from polyeugenol to polyeugenoxy acetic acid via hydroxyl groups. The resulting molecularly imprinted membrane (MIM) in the form of hollow fiber has better porosity, absorption, flux values and is highly selective in transport, with the order of selectivity, namely urea > creatinine > vitamin B12.

Abstract

ABSTRACT. In 2022, Indonesia will experience a major problem with clean water, almost 119 million people do not have access to clean water and are forced to consume unsuitable water. This problem is caused by poor water management and the high cost of separating using a reverse osmosis membrane. The abundance of seawater in Indonesia and Jepara in particular has encouraged researchers to create alternative desalination membranes that are efficient and selective using Hollow Fiber Desalination Imprinted Membranes (HFDIM), which are available on the market with better quality. Hollow Fiber uses an imprinted method that has good efficiency and selectivity. The variations used in this research were variations in seawater dilution concentration of 0, 3, 5, and 10 times. In tensile, biodegradable, contact angle, TGA, porosity, water absorption, flux, and transport tests, the best results were obtained using HFDIM at varying concentrations of 10 times dilution solutions with a percentage of 86.67% in the receiving phase and 10.89% in the feed phase. on HFDNIM it is 48.33% in the receiving phase and in the feed phase it is 50%.

Abstract

Penelitian mengenai dekolorisasi larutan remazol black B (RBB) menggunakan metode Fenton-like telah dilakukan dengan memanfaatkan timbal dioksida (PbO₂) sebagai material alternatif dalam metode Fenton. PbO2 diperoleh dari konversi limbah elektroda baterai dengan menggunakan oksidator kuat H2O2 dan NaOCl. Tujuan penelitian adalah mensintesis timbal dioksida dari Pb pada limbah baterai dan menguji potensi dekolorisasi larutan remazol black B. Timbal dioksida disintesis dengan menggunakan H₂O₂ dan NaOCl dan dilanjutkan dengan pengeringan pada suhu 200°C dan 300°C. Hasil sintesis kemudian dikarakterisasi menggunakan SEM-EDX untuk mengetahui morfologi serta komposisi unsur penyusun. Uji potensi timbal dioksida dalam proses dekolorisasi larutan RBB dilakukan dengan metode Fenton-like, yang ion Fe²⁺ pada metode Fenton konvensional digantikan oleh  Pb2+ dari timbal dioksida. Timbal dioksida dalam dekolorisasi bereaksi dengan H₂O₂ membentuk radikal •OH yang memiliki potensial oksidasi tinggi. Sejumlah PbO2 ditambahkan ke dalam 100 mL larutan remazol black B dengan konsentrasi 25 ppm, kemudian diproses mengikuti prosedur metode Fenton. Hasil dekolorisasi dianalisis menggunakan spektrofotometer UV-Vis. Hasil karakterisasi menunjukkan bahwa unsur utama penyusun oksida adalah Pb dan O, sesuai dengan prediksi. Timbal dioksida yang disintesis menggunakan NaOCl mampu menghilangkan warna larutan hingga 99,37%, sedangkan produk yang disintesis menggunakan H₂O₂ menunjukkan kemampuan dekolorisasi sebesar 94,16%.

Abstract

Research of chromium (VI) separation has been done using polymer inclusion membrane (PIM) method. This study aims to generate PIM, separate the metal ion chromium (VI) using PIM and determine the effect of the concentration of the feed phase, the thickness of the membrane and the amount of usage of the membrane for ion chromium (VI) diffusion.Polymer inclusion membrane (PIM) was made by mixing Aliquat 336-TBP as carrier compounds, PVC as the base polymer, DBE as a plasticizer and THF as a solvent. PIM membrane was placed between the source of analyte as a feed phase and result of the separation as a receiver phase. Feed phase was electroplating waste metal containing chromium (VI) at pH 4, while the receiver phase was a 2 N NaCl solution with a pH 6.7. The change of variables in this study were the concentration of the feed phase at various dilution i.e., 100x, 50x and 10x, the thickness of the membrane i.e., 25 μm, 20 μm and 10 μm, and the time of membrane using i.e., 1, 2 and 3 times. The concentration of chromium (VI) diffused after separation process was analyzed by atomic absorption spectroscopy (AAS). The stability of membrane was observed by analyzing the presence of membrane’s component in the feed phase and in the receiver phase. The analysis was conducted by UV-Vis spectrophotometry. Meanwhile, scanning electron microscopy (SEM) analysis was used to determine the morphology of membrane surface.The results showed that the chromium ion concentration diffused from the feed phase was 99.24%, meanwhile the 85.88% of it diffused to the receiving phase. The highest Cr(VI) ions diffusion was occured at the first use of PIM membrane with a thickness of 10 μm and the concentration of the feed phase was 10.55 ppm (resulted from 100 times dilution). Therefore, it can be concluded that the diffusion of chromium (VI) ion was influenced by the concentration of feed phase, the thickness of membrane and the number of membrane application.

Abstract

Sintesis Ionic Imprinted Polymer (IIP) dilakukan dengan variasi penambahan crosslinker PEGDE (Polyethylene glycol diglycidilether) yang kemudian diuji selektivitas IIP terhadap ion logam Fe melalui proses adsorpsi. IIP merupakan metode mencetak ion logam yang terikat dalam polimer, selanjutnya dilepaskan dari matriks polimer menghasilkan cetakan yang sesuai terhadap ion target. Tujuan penelitian ini untuk menghasilkan IIP dan NIP dari polieugenol dengan variasi penambahan crosslinker PEGDE perbandingan sebanyak  1, 2 dan 3 mol, mengetahui pengaruh jumlah mol crosslinker terhadap selektivitas adsorpsi IIP yang melibatkan rongga imprint/cetakan, serta mengetahui pengaruh logam kompetitor terhadap selektivitas adsorpsi IIP terhadap logam Fe. Selektivitas adsorpsi ion logam Fe(III) dengan penambahan crosslinker PEDGE 3 mol lebih besar dibandingkan dengan penambahan crosslinker PEGDE 1 dan 2 mol. Selektivitas adsorpsi Fe lebih besar pada Fe-Cr dibandingkan dengan Fe-Cd dan Fe-Pb.Influence of Crosslinker Mole Amount on the Selectivity IIP-Based Polyeugenol Towards Fe(III). The synthesis of IIP (Ionic Imprinted Polymer) was carried out using PEGDE (Polyethylene glycol diglycidilether) crosslinker addition in various moles which was then tested for IIP selectivity for Fe metal ions through the adsorption process. IIP is a method of metal ions printing which are bound in a polymer, then released from the polymer matrix to produce a suitable mold for the target ion. The purposes of this study were to produce IIP and non imprinted polymer (NIP) from polyeugenol with the addition of various moles of PEGDE crosslinkers as much as 1, 2 and 3 moles, and to determine the effect of the number of mole crosslinkers on the selectivity of IIP adsorption involving imprint/mold cavities, and the effect of competitor metals on IIP adsorption selectivity towards Fe metal. The selectivity of Fe (III) metal ion adsorption with the addition of 3 mole PEDGE crosslinkers was greater than the addition of 1 and 2 moles PEGDE crosslinkers. The selectivity of Fe adsorption is was greater in Fe-Cr compared to Fe-Cd and Fe-Pb.
