Özet

Hydroxyethyl sulfonamide function supported on styrene-divinyl benzene (9% mol/mol) bead resin is presented as mercury selective reagent. The resin product with 3.49 mmol g(-1) of 2-hydroxyethyl sulfonamide content removes reasonable quantities of mercuric ions (0.83-1.64 mmol g(-1)) from aqueous solutions of HgCl2, Hg (CH3COO)(2) and Hg (NO3)(2), in non-buffered conditions. Experiments showed that, the resin is able to extract mercury selectively, in the presence of foreign ions such as Zn(II), Cd(II), Fe(III), and Pb(II). Only negligible amount of sorption was detected for the case of Fe(III) (0.31 mmol g(-1)).
