This study aimed to synthesize chitosan crosslinked by sodium tripolyphosphate with different concentrations and optimize it for Ni(II) adsorption in a batch system. The BET analysis the solubility/swelling test showed that as crosslinking degree increased, surface area total pore volume decreased while physicochemical properties improved. effect of initial pH temperature on was studied system, thermodynamic parameters were calculated. In order enhance capacity chitosan, Response Surface...
Waste chloride pickle liquors from hot-dip galvanizing plants, steel plants and flue dust contain reasonable amounts of heavy metals such as Zn, Cr, Ni, etc. Iron is invariably associated with most these materials comes into solution during leaching. Thus, the synergistic extraction zinc(II) iron(III) leach solutions in tri-n-butyl phosphate (TBP)–di(2-ethylhexyl) phosphoric acid (D2EHPA) system diluted kerosene was investigated. The Zn Fe concentrations liquor used present study were 2 g/L....
This study investigates the adsorption of Ni(II) and Cd(II) ions from single binary metal ion solutions onto chitosan crosslinked beads, which was accomplished by an environmentally-friendly crosslinker, sodium tripolyphosphate. The synthesized adsorbents were characterized swelling test, BET SEM, tested for uptake after optimizing experimental factors, including adsorbent concentration (0.55 g/L) initial pH (6.5). single-ion equilibrium data fitted well Langmuir model. In system, a decrease...
