STUDY ON THE MECHANISM OF EXTRACTION OF MERCURY(Ⅱ) CHLORIDE BY PRIMARY AMINE N1923
Abstract:
In this paper the mechanism of extraction of mercury (Ⅱ) chloride by primary amine N1923 has been proposed. It shows that mercury chloride can be extracted by N1923 at pH>3.0. The composition of the extracted complex has been determined by isomolar continuous variation and saturation volume methods, IR and NMR measurements. The mechanism of the reaction is found to be as follows: HgCl2+RNH2(o)⇌RNH2·HgCl2(o) And amine acidified by hydrochloric acid can extract mercury(Ⅱ) chloride through the adduct formation 2RNH3Cl(o)+HgCl2⇌2RNH3Cl·HgCl2(o)
