有机高分子Schiff碱对金属离子的螯合作用已引起人们的兴趣。硅胶为无定形高比表面无机高分子,通过氯甲基化,可进行多种化学反应而形成各种表面基团。本文报道四种新型硅胶表面Schiff碱(图1),考察了它们对Cu~(2+),Co~(2+),Cd~(2+)和Pb~(2+)的配位作用。
Organic polymer Schiff base chelation of metal ions has attracted people’s interest. Silica gel is an amorphous high specific surface inorganic polymer. Through chloromethylation, a variety of chemical reactions can be carried out to form various surface groups. In this paper, four novel Schiff bases on silica gel surface were reported (Fig. 1). The coordination of Cu2 +, Co2 +, Cd2 + and Pb2 + was investigated.
