A novel strategy for the separation of cadmium from base metals in chloride medium by anion exchange based on formation halo-complexes is presented this article. Instead using excess Br− or I− feed solution, resin fibre was first preloaded with Cd2+ adsorption Cl− solution. Thus, consumption iodide bromide minimized while promising high stability Cd2+. The thermodynamics and kinetics were studi...

In this study, a pristine biochar (BC) and MgCl2-modified (MBC) were prepared using Pennisetum sp. straw for removing Cd2+ from aqueous solutions. Scanning electron microscope (SEM) imaging combined with energy dispersive X-ray spectroscopy (EDX), photoelectron (XPS), Fourier transform infrared (FTIR), as well the surface area porosity analyses used to reveal physico-chemical characteristics of...

Biochar prepared from agricultural waste resource coconut shells was used as the original charcoal, which oxidatively modified and characterized using batch adsorption tests before after modification by SEM, FTIR, surface area, elemental analyses. The removal capacity mechanism of biochar for Pb2+ Cd2+ in water were investigated, its kinetics thermodynamics discussed. findings demonstrated that...

In order to investigate the adsorption performance of black fungus bran biochar on Cu2+, Cd2+ and Pb2+ in water, waste was used as raw material prepare by oxygen-limited pyrolysis at 350?, 550? 750?, then experiments were conducted different pH, reaction time initial concentration. Thus, investigated

High-surface-area mesoporous MgO-templated nanocarbons made with reinforcing fibres from scrap tyres and a bituminous waste as carbon precursor were employed for the simultaneous adsorption of Cd and reactive Cibacron Brilliant Yellow 3G-P dye. A commercial activated carbon (AC) Darco KB-WJ was also used for comparison purposes. The effect of the pH of the solution was studied to establish whet...

Eggshell (ES) is an alternative source of calcium carbonate that efficiently removes heavy metals in aqueous solution. The adsorption capacity ES depends on their physico-chemical properties and the influence experimental conditions, but majority reports, not all reaction parameters related to process are available, mechanism systematically studied. In this contribution, use waste reported esta...

Cadmium is a major heavy metal found in polluted aquatic environments, mainly derived from industrial production processes. We evaluated the biosorption of solubilized Cd2+ using the extracellular polymeric substances (EPS) produced by Bacillus sp. MC3B-22 and Microbacterium sp. MC3B-10 (Microbactan); these bacteria were originally isolated from intertidal biofilms off the coast of Campeche, Me...
