In this study, lignin was isolated from rice (Oryza sativa L.) husk using alkaline extraction method and used as an adsorbent for aqueous solutions of methyl orange (MO) bromothymol blue (BTB). The equilibrium removal rate MO found to be at 61.4%, with experimental adsorbate uptake, qe, 1.23 mg·g-1, achieved 150 minutes contact time. For BTB, the 78.3%, qe 1.57 Pseudo-first order (PFO) pseudo-s...

Abstract This study has Zinc oxide (ZnO) nanoparticles (NPs) synthesized from the leaf extract of Costus Afers via a green approach. The zinc nanoparticle (ZnO NPs) showed excellent adsorption capabilities towards Cd (II) and Pb ions. ZnO NPs were characterized by Fourier Transform Infrared (FT-IR), Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD). formation was confirmed absorption ...

In the present work, adsorption behavior of Eriochrome Black T (EBT) on waste hemp activated carbon (WHAC) was examined. The surface WHAC modified by H3PO4 acid treatment. and structural characterization adsorbents carried out using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) analysis. effect influential parameters (pH, contact time, dosage, initial concen...

The efficiency of Azadirachta indica (neem leaves) on the removal Pb(II) ions by adsorption from aqueous solution was investigated in this study. these leaves (without chemical or thermal treatment) for has not previously been reported. Batch experiments were performed to study effect particle size, pH, adsorbent dose, contact time, initial ion concentration, and temperature. maximum 93.5% achi...

Used for various high-tech applications, cerium is an important rare earth element (REE), and its sorption on solids also considering purification environmental radioactive waste disposal. In view of the industrial terms, it to remove Ce3+ ions from aqueous solution. Magnetite magnetic olive pomace nanocomposite were thus fabricated by a partial reduction co-precipitation approach. The structur...

Abstract Nanostructured bio-adsorbents were prepared by physical or chemical activation of the residue supercritical extraction raspberry seed. Their physicochemical properties determined elemental analysis, low-temperature nitrogen adsorption/desorption, Boehm titration and scanning electron microscopy. The biocarbon obtained as a result precursor showed basic character surface its S BET was 7...

Abstract A novel nanocomposite was prepared by hybridizing polyacrylic acid/maleic acid with nano copper oxide (PAACMA/CuO) for the sorption of 60 Co (II) and 152+154 Eu (III) radionuclides from an aqueous solution. Nano-CuO biochemically produced hydrolysing its salt in presence Aspergillus terreus fungus. The PAACMA/CuO characterized using a variety analytical techniques. optimum conditions (...

removal of typical contaminants like aromatic amines (e.g. 1-naphthalen amine, diphenyl amine, aniline, 2 and 6-dimethyl pyridine) from water during one-stage process is a method to purify water wherein organic contaminants get extracted from water by bentonite. in this study the effects of ph, stirring time, stirring speed, bentonite mass and bentonite size (mesh) were investigated. also, the ...

background dyes are one of the most important industrial pollutants, especially in textile industries. many methods have been proposed in order to remove color from wastewater among which, adsorption is more acceptable due to the ability for its use in the large scale. objectives the objective of this study was to investigate pumice as an inexpensive adsorbent for removal of methylene blue from...

Bu çalışma, sulu çözeltilerden Mn2+ iyonlarının uzaklaştırılması için ham portakal kabuğunun (HPK) değerlendirilmesini anlatmaktadır. Adsorpsiyon verimi pH, başlangıç metal iyonu derişimi, temas süresi ve sıcaklık gibi farklı değişkenlerin etkileri araştırıldı. için, en iyi konsantrasyonunun 100 mg/L, adsorpsiyon süresinin dakika çözelti pH'ının 5.37 olduğu şartların uygun çalışma koşulları bel...
