Abstract—A new-posite ulant, Polysilicate
However, there is growing concern about influence of
Aluminum Ferric-Chitosan (PSAF-CTS), was prepared
ulants on environment and effluent quality. To
using polysilicate aluminum ferric (PSAF) and
achieve widespread use and no pollution, people focus on
Chitosan(CTS). The performance of PSAF-CTS was
compounding new-type ulants and are deeply
analyzed by testing turbidity and chrominance of
attracted by derivative of chitin since 1990s
papermaking wastewater, as well as removal efficiency of
[1-2].Chitosan(1,4)-2-amino-2-deoxy-β-D-glucan[(C6H11
Cu2+, Ni2+, Zn2+, Cd2+, Cr6+ of heavy-metal wastewater. The
O4N)n,CTS],a deacetylation derivative of chitin with a
orthogonal experiments showed that the optimal
degree of deacetylation 50-100%, can be extracted from
preparation conditions were pH , material ratio 1:1,
the exoskeleton of crustacean and insects. CTS can be
reaction temperature 70°C, and reaction time 24 h. For
