background nowadays, removal of heavy metals from the environment is an important problem due to their toxicity. objectives in this study, a modified method was used to synthesize chitosan-coated magnetite nanoparticles (ccmn) to be used as a low cost and nontoxic adsorbent. ccmn was then employed to remove hg2+ from water solutions. materials and methods to remove the highest percentage of mer...

To counter environmental threats to the water resources polluted by NH, which is common in wastewaters and agricultural runoff, adsorption using mesoporous functional materials represents a promising alternative to existing treatment methods. In this study, adsorption of NH ions from aqueous solutions was investigated on arene- and propylsulfonic acid functionalized SBA-15 mesoporous silica mat...

the aim of this study is to investigate the nitrate adsorption on granular ferric hydroxide (gfh). the effect of factors such as initial concentration of nitrate, ph, contact time, and adsorbent mass were determined. the study was done in laboratory–scale in which synthetic nitrate solutions in a batch reactor were placed in contact with the adsorbent to model adsorption kinetics. it was found ...

background and purpose: phenol and derivatives are common pollutants of drinking water which are blamed for crucial adverse effects such as poisoning, cancer, and malformation. in this study, an activated carbon of miswak’s root (mr) was used for the removal of phenol from aqueous solutions as a low-cost and high surface adsorbent. materials and methods: adsorption experiments were then conduct...

In this work, organomodified nanoclay has been used as the adsorbent for the removal ofbasic blue 41, cationic dye from an aqueous solution. The performance of the organomodified nanoclay was tested in a batch system under varying pH (2–12), adsorbent dosage (0.1–2 g L-1), initial dye concentration (10–60 mgL-1), and contact time (5- 100 min). The best conditions were achieved at pH of 7,...

Activated carbon derived from biomass waste, namely palm shell, was evaluated as a potential adsorbent for the removal of Reactive Black 5 dye (RB5) from an aqueous solution. This work focused on the equilibrium isotherms and the kinetics of the adsorption process. Batch adsorption tests were conducted to determine the effects of various parameters, such as contact time, RB5 concentration, adso...
