Optimization of Copper and Zinc ions removal from aqueous solution by modified Nano-bentonite using Response surface methodology
Presence of heavy metal ions in wastewater is an important public concern. Adsorption are commonly used technique to remove various pollutants, including the ions, from contaminated water sources. However, common methods for adsorption are not completely efficient at low ion concentrations and the adsorbent should be improved in order to reaching the acceptable levels of adsorption efficiency. ...
متن کاملPreparation of magnetic chitosan/Fe-Zr nanoparticles for the removal of heavy metals from aqueous solution
Copper and hexavalent chromium are heavy metals that are harmful to human health. Natural adsorbent chitosan, due to its considerable properties such as the presence of functional groups of –NH2 and -OH, non-toxicity, low cost, and biocompatibility, has gained much attention in pollutant removal. Therefore, in the present study, adsorption of chromium (VI) and copper (II) ions was conducted in ...
متن کاملAdsorption Of Ternary Metal System Onto The Sawdust Of Locust Bean Tree (Parkia biglobosa): Equilibrium, Kinetics And Thermodynamics Studies
The use of raw sawdust, RSD, of locust bean tree (Parkia biglobosa), a low-cost, locally available agroforestry waste as an adsorbent for removing a ternary mixture of heavy metals comprising of copper, lead and nickel (TMS) from aqueous solution was examined. Equilibrium data obtained from batch adsorption experiments were analysed with Langmuir, Freundlich and Temkin isotherm models, with Lan...
متن کاملAdsorption of Lead and Copper by a Carbon Black and Sodium Bentonite Composite Material: Study on Adsorption Isotherms and Kinetics
The efficiency of using a composite of carbon black and sodium bentonite in treating drinking water contaminated with lead and copper ions was analysed. The effects of pH, contact time, concentration and adsorbent dosage using an adsorbent composite of 20 % sodium bentonite and 80 % carbon black were studied. The adsorption data was tested with respect to Langmuir, Freundlich and Temkin iso...
متن کاملBiosorption of Nickel Ion by Chitosan-immobilized Brown Algae Laminaria japonica
Highly toxic nickel is released into the environment from a number of industrial processes, but current techniques for its removal are expensive and may cause secondary pollution. We developed a biosorbent of chitosan-immobilized brown algae (Laminaria japonica). The effects of different parameters on the adsorption capacity and biosorption-desorption of Ni from aqueous solution were evaluated....
