摘　　要：研究了碳酸铜钙(CaCu3Ti4O12,CCTO)粉体对偶氮染料刚果红(Congored,CR)及丽春红2R(Ponceau2R,PR)的吸附脱色作用。结果表明,CCTO粉体对CR及PR均具有较好的脱色作用,但对CR的吸附脱色作用优于对PR的吸附脱色作用。CCTO粉料对30mg/L的CR溶液的脱色率达到了98.5%,对10mg/L的PR溶液的脱色率达到了78.4%。The absorption and decolorization effect of calcium copper titanate powders on azo dyes-congo red (CR) and ponceau 2R (PR) was investigated. The results show that CCTO powders have good absorption and decolorization effect on CR and PR, but the absorption and decolorization effect of CR is better than that of PR. The decolorization rate of CCTO powders on CR solution (30 mg/L) and PR solution (10 mg/L) reaches 98.5 % and 78.4 %, respectively.
