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 (...

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...

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...

Saccharomyces cerevisiae biomass was activated chemically, and its ibuprofen (IBP) biosorption capabilities were assessed regarding IBP removal from an aqueous solution. The effects of pH (2-10), contact time (0-90 min), concentration (5-35 mg L-1), temperature (20, 30, 40°C) evaluated in batch studies. Higher rates found at 2.0. pseudo-second-order kinetic model best described the experimental...

Antibiyotik kalıntılarının su kaynaklarındaki toksisitesi çevreyi olumsuz etkilemektedir. Son yıllarda yapılan çalışmalar antibiyotikler gibi organik kirleticilerin ucuz ve çevreye uyumlu adsorbentlerle sulu çözeltilerden giderimine odaklanmıştır. Bu çalışmada, doğal Manisa-Gördes klinoptiloliti oksitetrasiklin hidroklorür (OTC-HCL) adsorpsiyonu, kesikli sisteminde 298-323 K'de incelenmiştir. p...

Abstract The adsorption potential of raw pomegranate peel powder (PMPP) for lead (Pb) ions was investigated via batch mode at varying initial adsorbate concentration, contact time, and adsorbent concentration. PMPP extensively characterized using Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energy-dispersion (EDX), thermogravimetry...
