Kinetic study of heavy metal ions removal from aqueous solutions using activated pumice stone
Background: The presence of heavy metals in aquatic and terrestrial ecosystems causes harmful effects to living organisms in the environment. This research aimed to determine the potential of activated pumice stone (APS) as a sorbent for the removal of Cd, Cu, and Zn from wastewater. Methods: This research was conducted during 2013 on a laboratory scale. The study was performed using batch exp...
متن کاملThe removal of heavy metal ions from aqueous solutions by novel pH-sensitive hydrogels.
Novel non-ionic hydrogels were synthesized by radical homopolymerization of N-vinyl-2-pyrrolidone (VP) or by radical copolymerization of VP with methylacrylate (MA). A macroinimer (MIM) was used as a crosslinker and initiator, as well. The percentage of mass swelling ratios (S(M)), the molecular weight between crosslinks (M(c)) and Young's modulus of the hydrogels were investigated. The hydroge...
متن کاملSorption of Heavy Metal Ions from Aqueous Solutions: A Review
Sorption techniques are widely used to remove heavy metal ions from large volumes of aqueous solutions. Herein, the natural and some artificial materials, such as clay minerals, biosorbents, carbon-nanomaterials, metal oxides, are reviewed as adsorbents in the removal of different heavy metal ions, such as Ni(II), Cu(II), Pb(II), Cd(II), Cs(I), Eu(III), Th(IV), Cr(VI) from large volumes of aque...

متن کاملPreparation of Nanochitosan as an Effective Sorbent for the Removal of Copper Ions from Aqueous Solutions
The most important pollutants in wastewater are heavy metal ions. In this paper, the effects of various parameters such as pH, contact time, initial concentration, and temperature on the adsorption of Cu (II) by nanochitosan (NCS) was investigated in batch experiment. Nanochitosan was prepared based on ionic gelation and characterized by means of Fourier Transform Infrared Spectroscopy (FTIR),...
