interacting laterally between
them. After that, surfactant adsorption occurs through hydrophobic
interactions between hydrocarbon tail-groups, which results
in the formation of discrete surface aggregates termed ad-micelles.
Because of the amphiphilic character of surfactants, ad-micelles
are aggregates in which there are regions of different polarity,
and acidity, etc. This feature makes these aggregates extremely
versatile extractant because of the number of interactions which
they can establish with analytes. According to our literature
survey, the combination of SDS-A modified with 2-hydroxy-3-
((1-H-indol 3-yle)phenyl) methyl) 1-H-indol (2-HIYPMI) for
preconcentration and separation of metal ions is new.
The purpose of this work is to investigate the feasibility of
adsorption of these ions including Co2+, Cu2+, Zn2+ and Pb2+ ions
on SDS-A modified with 2-hydroxy-(3-((1-H-indol 3-yle)phenyl)
methyl) 1-H-indol (2-HIYPMI).
