Abstrakt:
Cyclic voltammetry of Cu2+ on the carbon paste electrode modified either
with montmorillonite SAz-1 or with montmorillonite SAz-1 pretreated with hexadecyltrimethylammonium
cation was performed to find the hexadecyltrimethylammonium
cation influence on the Cu2+ sorption. In addition, the hexadecyltrimethylammonium
presence in the sorption solution was studied, too. In this case, a
significant inhibition on the Cu2+ sorption was found. The inhibition is supposed to be
a consequence of the competitive sorption of HDTM and Cu2+.
