咪唑银配位聚合物吸附偶氮染料研究

Adsorptive Removal of Azo Dyes by {Ag(im)}n Coordination Polymer

以咪唑银配位聚合物{Ag(im)}n作吸附剂,对偶氮染料刚果红和甲基橙的吸附进行了研究,结果表明:刚果红的最佳吸附条件是吸附剂加入量为31.5 mg,温度为30℃,pH值为3,吸附时间为70 min,最高染料脱除率为90.7%;甲基橙的最佳吸附条件是吸附剂加入量为36.7 mg,温度为30℃,pH值为2,吸附时间为50 min,最高染料脱除率为58.3%。

Adsorptive removal of Congo red and Methyl orange azo dyes using{Ag（im）} n coordination polymer were investigated. The result showed that the optimization factors is adsorbent of 31.5 mg, temperature of 30℃, pH value of 3, 90.7% Congo red dye was removed by reaction time 70 min; adsorbent 36.7 mg, temperature of 30 ℃, pH of 2, equilibrium time 50 min, Methyl orange dye maximum removal ratio is 58.3%.
