Abstract

Aluminium(III)-tartrate (Al-T) complex is a compound that commonly used as mordent in textile dyeing. This complex is soluble in hot water; thus, information on the isolation of crystallised Al-T is limited. Isolation of crystallised Al-T is needed to gain a high purity complex for further application in the textile industry. This study aims to synthesize and isolate crystalline complex of Al-T. Hydrothermal method was used to obtain the targeted complex. Effects of tartrate precursor and Al(III):tartrate mol ratio in the synthesis of Al-T complex were also investigated. The synthesis was done at 150 °C for 24 hours in several Al(III):tartrate mol ratios (1:2, 2:1, and 2:3) using two different tartrate precursors, namely L-tartaric acid and KNa-tartrate. The synthesized complexes were identified by infrared spectroscopy and powder-XRD analyses, and then further characterised by UV Vis - DRS, DTA-TGA, and SEM. Experimental data shows that the mol ratio affects the precipitation of the Al-T complex, in which a white crystalline solid was only precipitated out from the 2:1 reaction by both tartrate precursors. Different tartrate precursors used in the synthesis may alter the crystallization and result in an Al-T complex with slightly different thermal decomposition profile, UV-Vis DRS spectra profile, and different yield due to the different nature of the tartrate precursor. This finding is expected to support the possibility of Al-T mass production as mordent in textile dyeing

Abstract

Al(III) complex with 1,4-benzenedicarboxylate ligand (Al-BDC) is a porous material that has the potential to be developed as an adsorbent or photocatalyst. This complex is often obtained by the solvothermal method at high temperature. This paper reports the synthesis of Al-BDC complex by solution method at room temperature from two different types of Al(III) salts, namely nitrate salt (complex 1) and chloride salt (complex 2). The synthesis of Al-BDC was conducted with Al(III):H2-BDC mol ratio of 2:3. The synthesized complexes were characterized by ATR-IR, powder XRD, UV Vis–DRS, and DTA–TGA. The results showed that white powders were obtained with a yield of 75.8% (complex 1) and 65.7% (complex 2). The presence of BDC ligands in both complexes was confirmed by the presence of typical absorption bands of C=O, C-O, and Al-O functional groups in their infrared spectra. Both complexes have different surface morphology and average crystallite sizes (28.63 nm – complex 1; 34.98 nm – complex 2), but the powder X-ray diffraction patterns, DTA-TGA thermograms, UV Vis-DRS spectra, and band gap energy values ​​of both complexes are considerably identical. Powder XRD diffraction analysis of both complexes shows a pattern that is identical to the known compound with a formula of {[Al(OH)(BDC)]·(H2BDC)0.69}n(CCDC No. 2179625) in which the compound forms 3D polymeric structure with terephthalic acid occupies the voids.

Abstract

Mikroplastik sebagai hasil degradasi sampah plastik besar telah mencemari lingkungan perairan. Mikroplastik di perairan ini berpotensi untuk terakumulasi dalam tubuh organisme termasuk ikan. Penelitian ini bertujuan untuk menganalisis dan membandingkan mikroplastik pada insang, saluran pencernaan dan daging ikan lemuru (Sardinella lemuru) yang didaratkan di Pelabuhan Sendangbiru, Malang. Pengumpulan sampel ikan dilakukan pada Bulan Maret 2020 dengan membeli  10 ekor ikan hasil tangkapan nelayan dengan kisaran ukuran 11−15 cm. Analisis laboratorium dilakukan mulai dari mengukur panjang (cm) dan berat (g) ikan, melakukan pembedahan masing- masing organ, destruksi bahan organik dan identifikasi mikroplastik menggunakan mikroskop. Destruksi bahan organik dilakukan dengan merendam sampel organ yang sebelumnya telah ditimbang berat basahnya menggunakan larutan H2O2 30 % dan Fe(II) 0.05 M. Sampel diinkubasi selama 24 jam hingga sampel beserta bahan organik hancur. Tiga jenis mikroplastik ditemukan di seluruh sampel organ ikan dengan dominansi jenis fiber (54 %), diikuti oleh fragmen (43 %) dan film (3 %). Keberadaan mikroplastik pada ikan dapat dikaitkan dengan keberadaan mikroplastik di perairan. Komposisi jenis mikroplastik  berbeda  untuk  setiap  organ.  Fragmen  ditemukan  paling  banyak  pada insang, sedangkan pada saluran pencernaan dan daging didominasi oleh jenis fiber. Film ditemukan dengan jumlah yang paling sedikit pada ketiga organ. Keberadaan mikroplastik pada insang dan saluran pencernaan berkaitan dengan interaksi langsung ikan dengan lingkungan melalui pernapasan dan proses makan, sedangkan mikroplastik pada daging karena adanya proses translokasi atau perpindahan antar organ

Abstract

Pyrolusite, a manganese ore from East Nusa Tenggara (Indonesia), was explored and utilized in the production of crystalline Mn(II) based coordination polymers materials, namely Mn(II)-terephthalate and Mn(II)-tartrate. The pyrolusite was extracted into Mn(II) sulfate by acid method in the presence of hydrogen peroxide. The Mn(II) sulfate, characterized by X-ray fluorescence (XRF), infrared spectroscopy (IR), and X-ray powder diffraction (PXRD), was then used as a precursor in the production of crystalline Mn(II) based coordination polymers materials using a solution method at room temperature. Two ligands, terephthalate and tartrate, were used separately, in which the terephthalate complex was prepared using a layered solution technique, while the tartrate complex was made using a direct mixing technique. The synthesized Mn(II) coordination polymers were then characterized by FTIR and PXRD. This study finds that the manganese ore was extracted as MnSO4 compounds with purity of 96.88% and average crystallite size of 103 nm. The MnSO4 was successfully converted into crystalline Mn(II) coordination polymers materials. Based on IR and PXRD analyses, the crystalline products were identified as Mn(II)-aqua-terephthalato and Mn(II)-aqua-tartrato hydrate complexes, in which the former complex display 3D networks and the latter complex display 2D sheets of polymeric structures.
