Abstract

The present study was undertaken to develop a cost effective biosorbent and to study the biosorption process involved in the adsorption of heavy metal-contaminated textile wastewater using the developed biosorbent. Biomass chicken feathers was activated by Na2S 0.1 N to produce adsorbent for lead in aqueous solution. This study focuses on the effectiveness of lead removal by batch adsorption method. The feather samples both activated and non-activated with adsorbed Pb (II) ions were analyzed by spectroscopic methods (Surface Area Analyzer, Atomic Absorption Spectroscopy and Fourier transform infrared spectroscopy). Particularly, the effect of pH, agitation time, adsorbent concentration, and particle size were considered. Optimum adsorption pH values of Pb (II) for activated and non-activated feathers were 8 whereas optimum adsorption contact time of Pb (II) for activated and non-activated feathers were 60 minutes and 90 minutes respectively. At the optimal adsorption conditions, adsorption ratio could get to 97.52% for activated feathers and 98.67% for non-activated feathers. The higher concentration of lead has a greater adsorption as well as high adsorption capability of feathers. The Freundlich adsorption model agrees well with experimental data, because of the high correlation coefficient that the former exhibited, thus, indicating to the applicability of multilayer coverage of the Pb (II) on the pores of adsorbent surface. The applicability of the Ho and Lagegren kinetic model has also investigated. Lead ions from the sample of textile wastewater were adsorbed on activated feathers with efficiency up to 90%. Laboratory tested and proven more effective and efficient in removing Pb (II) ions from aqueous solution by using activated feathers. The low cost and simplicity of the technique hold great potential applications in environmental protection.Keywords: Adsorption; Biomass of chicken feather; Heavy metals; Pb (II) ions; Textile wastewater

Abstract

Research of Pb ions adsorption with chicken feathers adsorbent has been conducted. This research aims to determine adsorption properties of activated chicken feathers and the chicken feathers that were not activated by Na2S for Pb ions. The adsorption process was conducted by batch method with variation of the concentration, pH, and contact time. Pb content in solution is characterized by AAS spectroscopy (Atomic Absorption Spectroscopy). The results show that the contact time and pH condition for adsorption equilibrium are 60 min for activated chicken feathers and 90 min for chicken feathers which were not activated by Na2S at pH 8. Pb absorption by chicken feathers followsFreundlich isotherm and the reaction kinetics follow the Ho equation.

Abstract

Pemanfaatan limbah tempurung kelapa (Cocos nucifera L) sebagai komposit agen antibakteri logam Ag/Alumina- karbon aktif untuk membuat Lapisan antibakteri pada pengolahan limbah cair terkontaminasi mikrobiologi pada rumah sakit. Metode penelitian dilakukan dengan cara preparasi Ag/Alumina-Karbon Aktif yang kemudian diujikan dengan bakteri pada berbagai perbandingan konsentrasi pengemban sehingga diketahui konsentrasi yang efektif untuk membunuh bakteri. Hasil percobaan menunjukkan penyerapan bakteri menggunakan bahan Ag/karbon-Alumina Aktif (Ag/KAA) dengan perbandingan karbon aktif: alumina 1 : 9 mampu mereduksi bakteri 10,47%. Semakin banyak penambahan karbon aktif pada komposit mampu mereduksi bakteri lebih banyak. Hasil penelitian digunakan sebagai dasar dalam penentuan konsentrasi yang tepat untuk digunakan dalam alat. Alat penyaring didesain dengan menggunakan reaktor dengan 2 kali penyaringan yaitu menggunakan Ag/KAA pada penyaringan pertama dan hanya KAA pada penyaringan kedua. Hasil penelitian berupa pembuatan komposit, aplikasi antibakteri, dan rancangan desain alat diharapkan dapat menjadi referensi baru dalam pengolahan limbah mikrobiologi rumah sakit.

Abstract

Dental caries is caused by the Streptococcus mutans bacteria, which causes a food deposit to harden and adhere to the tooth surface. Cavities will develop if food residue is not removed. Herbal plants, specifically sappan wood, can be used as an antibiotic. The purpose of this study was to look at the secondary metabolite content of sappan wood extract, antibacterial activity, and the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of sappan wood extract against Streptococcus mutans bacteria. This research method includes the maceration of sappan wood extract with 96% ethanol solvent, phytochemical screening of sappan wood extract, inhibition zone test with paper disc method, and MIC and MBC tests. Qualitative testing revealed that the sappan wood extract contained alkaloids, flavonoids, tannins, and saponins. Flavonoids, tannins, and saponins are all constituents of plants. Secang wood extract has antibacterial activity against Streptococcus mutans, as evidenced by the formation of inhibition zones at concentrations of 20%, 40%, 60%, 80%, and 100%, namely 8.75±0.354; 11±1.41;, 12.75±0.354; 16.25±0.354; and 17.5±0.000 mm. Sappan wood ethanol extract had a MIC of 12.5% against Streptococcus mutans and an MBC of 25%.
