The aim of this study is to investigate the application of polypyrrole/ polyaniline (PPy/PANI) nanofiberfor Cu (II) sorption from paper mill wastewater. The tests and their optimization results were basedon the experiments design in three levels of variables using Taguchi method. The results showed thatin Copper removal tests, the pH of the solution was the most effective para...

The present work describes the synthesis of copper oxide nanoparticles (CuONPs) via a solution process with the aim of applying the nano-adsorbent for the reduction of methylene blue (MB) dye in alkaline media. These NPs were characterized via Field emission scanning electron microscopy (FE-SEM), X-ray diffraction, high-resolution Transmission electron microscopy (TEM), and ultra violet UV-visi...

Thermodynamic adsorption properties (differential enthalpy and entropy, spreading pressure and net integral enthalpy and entropy) of cassava flour were determined at 25, 30 and 35°C to provide information about the water and energy requirements for the sorption process. The Guggenheim–Anderson–de Boer (GAB), Peleg and Halsey models were found to adequately describe the sorption characteristics,...

The present investigation aimed to study and compare the efficiency of non-viable fungal isolates to remove divalent lead (Pb(II)) from aqueous streams. The selected fungal isolates showed identity with Aspergillus caespitosus, Aureobasidium sp. RBSS-303 and Aspergillus flavus HF5 as confirmed using gene sequencing of ITS regions of the ribosomal DNA (rDNA). The obtained equilibrium data for Pb...

The thermodynamic parameters viz. the standard free energy (∆Gº), Standard enthalpy change (∆Hº) and standard entropy change (∆Sº) were determined using the obtained values of distribution coefficient (kd) of U (VI) in two different types of soils (agricultural and undisturbed) by conducting a batch equilibrium experiment with aqueous media (groundwater and deionised water) at two different tem...

Agricultural solid waste (corn cob) has been investigated asbiosorbent for removal of metribuzin herbicide from aqueous solution. Parameters influencing extraction efficiency such as pH of the sample, contact time of sample with biosorbent, shaking time, temperature, heating time, sorbent dose were studied. Maximum sorption of metribuzinwas found at pH 5.0. The sorption of metribuzin on corn co...

The article provides an overview of the literature on the role of sorption detoxification using intestinal adsorbents (enterosorption method) in the multifaceted treatment of various diseases. The mechanism of action of adsorbents and their therapeutic effects are presented. We emphasized that intestinal adsorbent Enterosgel is a modern, effective, and safe detoxifying agent.
