kinetic and isotherm of hexavalent chromium adsorption onto nano hydroxyapatite
background : hexavalent chromium ( cr (vi)) is an important contaminant in surface and groundwater and its removal from contaminated water and wastewater has received interest in recent years. this study aimed to explain the removal process of cr (vi) from aqueous solution using nano hydroxyapatite (n-hap) as an adsorbent material. methods: cr (vi) removal experiments with the prepared n-hap we...
متن کاملHexavalent Chromium Removal from Aqueous Solutions by Adsorption onto Synthetic Nano Size ZeroValent Iron (nZVI)
The present work was conducted for the synthesis of nano size zerovalent iron (nZVI) and hexavalent chromium (Cr(VI)) removal as a highly toxic pollutant by using this nanoparticles. Batch experiments were performed to investigate the effects of Cr(VI), nZVI concentration, pH of solution and contact time variation on the removal efficiency of Cr(VI). nZVI was synthesized by reduction of ferric ...
متن کاملMalachite Green Adsorption Behavior of Polyurethane/Chitosan Composite Foam
A composite foam of polyurethane/chitosan with chitosan content of 20 wt% was successfully prepared as an adsorbent for the removal of malachite green from aqueous solution, the structures and properties were characterized by scanning electron microscope and Fourier transform infrared spectroscopy. The results showed open cell content of polyurethane/chitosan was more than 95% and open cell str...
متن کاملBionanocomposites based on layered silicates and cationic starch as eco-friendly adsorbents for hexavalent chromium removal.
Functional bionanocomposites based on two layered silicates, the commercial montmorillonite known as Cloisite®Na and a natural bentonite from Algeria, were prepared by intercalation of cationic starch, synthesized with two different degrees of substitution, 0.85 and 0.55. After characterization of the prepared bionanocomposites by XRD and zeta potential measurements, batch studies were conducte...
متن کاملAdsorption of hexavalent chromium by polyacrylonitrile-based porous carbon from aqueous solution
Owing to the unique microporous structure and high specific surface area, porous carbon could act as a good carrier for functional materials. In this paper, polyacrylonitrile (PAN)-based porous carbon materials (PPC-0.6-600, PPC-0.8-600, PPC-0.6-800 and PPC-0.8-800) were prepared by heating KOH at 600°C and 800oC for the removal of Cr(VI) from aqueous solution. The adsorbent was characterized b...
