The need to develop effective technology for the treatment of liquid effluent dye-intensive industries such as textile, rubber, paint, and printing is synonymous with save life-threatening risks posed by these carcinogenic mutagenic pollutants on human aquatic lives. Isotherms adsorption crystal violet (CV) activated carbon (AC) synthesized from rice husk are presented herewith elucidate mechan...
Acid and thermal treated sepiolite was organophilized by cationic exchange with several alkylammonium cations (octylammonium, hexadecylammonium, tetradecyltrimethylammonium, hexadecyltrimethylammonium). The adsorption capacity of BTEX from aqueous solutions evaluated through the isotherms performed in batch. results were analysed using three isotherm models: Freundlich, Langmuir Dubinin-Radushk...
The paper investigates the physicochemical regularities (kinetics and isotherm) of phosphorus beryllium recovery by sorbents based on polyacrylonitrile (PAN) fiber Fe(OH)3 obtained various methods: PAN or pre-hydrolyzed with precipitation FeCl3 ammonia, using ready-made electrochemically generated Na2FeO4, treated an alkaline solution as well their comparison granular aluminum oxide. Langmuir, ...
Abstract Adsorbed methane significantly affects shale gas reservoir estimates and transport in formations. Hence, a practical model for accurately representing adsorption behavior at high-pressure high-temperature is imperative. In this study, reliable mathematical framework that the absolute directly from low-pressure excess data applied to describe literature. This method provides detailed in...
In this research, adsorption experiments were carried out for removal of Basic Blue 41(BB41) dye from an aqueous solution, using coconut fiber particles (CFP) as a low-cost biosorbent. The characteristics of coconut fiber particles weredeterminedwith a scanning electron microscope (FE-SEM) and Fourier Transform Infrared (FTIR) techniques. The effects of initial pH, biosorbentdose, contact time,...
Isotherms of Zn 2+ ions adsorption by native and 3% H 2 SO 4 solution-treated leaves Acacia auriculiformis were plotted. The resulting isotherms processed using the Langmuir, Freundlich, Dubinin-Radushkevich Temkin models. It was found that these with earleaf acacia are most accurately described model modified Langmuir model. modification a solution contributes to an increase in maximum sorptio...
Environmentally, removing organic pollutants from industrial waste solutions is important. In this study, the potentiality of Thoron (TH) and Arsenazo III (ARZIII) was investigated using chemically stable zinc tungstate nanoparticles (ZW-NPs). The preparation ZW-NPs performed an eco-friendly solvo/hydrothermal technique as a sorbent. Complete characterisation before after adsorption processes X...
This study aimed to evaluate the methyl red (MR) removal efficiency from aqueous matrices using an eco-friendly anionic surfactant (a calcium surfactant, or CaSF), obtained frying oil residue. Data by infrared spectroscopy revealed several functional groups that favor capture of dye chemisorption forming hydrogen bonds and covalent interactions. The kinetic testing results fit pseudo-second ord...
This study focused on the synthesis of silica-coated magnetic Fe3O4 (Fe3O4@SiO2) nanoparticles and their application for improvement vapor-phase adsorption benzene. The Fe3O4@SiO2 were synthesized according to co-precipitation method, while characterization was performed using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) Brunauer-Emmett-Teller (BET) surface...
Polypores (woody pore fungi) biomass has been used as an biosorbent for the removal of Pb(II) and Cd(II) from aqueous solution under batch equilibrium experimental conditions. The resulting biosorbent is characterized by SEM and FTIR techniques. The effect of experimental parameters, such as solution pH, biomass dosage, contact time, initial metal ion concentration and temperature of Pb(II) and...
