Crosslinked amphoteric starches (CAS) with quaternary ammonium cationic
and carboxymethyl anionic groups were prepared by a microwave radiation method.
Their adsorption behavior for Cr(VI) was investigated. The results showed that high
the degree of substitution (DS) of modified starch was favorable to the synthesis by
the microwave heating and crosslinked amphoteric starches prepared with higher the
adsorption capacity than by the drying reaction. The adsorption capacity increases
with the increasing cationic groups and decreased with increasing degree of
substitution of anionic groups. The adsorption capacity was found to follow the
Langmuir isotherm. |
