Dependence of adsorption capacity of succinate functionalized linseed for Ni (II) adsorption on different factors

Abstract

An effective sorbent for removing Ni(II) from aqueous solutions was developed by chemical modification of a polysaccharide from linseed that provided multiple new functional groups and produced a succinate derivative (SRG), which was then converted into sodium salt (Na-SRG). To having good capacity for holding water, it was tested for its ability to remove Ni (II) from solution. The effects of initial concentration of Ni(II), the sorbent dose, temperature, time to contact, and the pH of the metal solution were investigated through batch adsorption tests using Na-SRG. All the tested parameters had prominent effect on the sorption capacity of Na-SRG in removing Ni(II). The Ni(II) reached equilibrium quickly in 30 min. Hence, Na-SRG is sorbent material of great choice to remove metals from polluted water.
