چکیده
In this work, locally available tea wastes were used as precursors for the development of cost-effective bio-sorbent materials heavy metal removal from wastewater. Chemical and thermal treatments to prepare magnetic/non-magnetic waste-based adsorbents discussed correlated their properties with corresponding Cr(VI) adsorption capacity. These bio-sorbents thoroughly characterized by FT-IR, PXRD, N2 adsorption-desorption surface area techniques Cr performance was investigated in batch reactor under different conditions such adsorbent dosage, initial concentration, solution pH contact time. Careful bleaching steps, incorporation magnetic iron nanoparticles judicious temperature resulted high performing biosorbents a complete at dosage 0.25 g/mL solution. on these found be fitting pseudo 2nd order kinetics.

متن کاملNanocrystalline Akaganeite as Adsorbent for Surfactant Removal from Aqueous Solutions
The present study presents the effective use of nanocrystalline akaganeite for the adsorption of an anionic (SDS), a cationic (CTAB), and a nonionic (tween80) surfactant from wastewater. Equilibrium experiments, as well as thermodynamic analysis, were performed. The maximum SDS adsorption occurs at the lowest pH value (5), the opposite is observed for CTAB (pH = 11), while for tween80, the chan...
