摘要:

本文将碳纳米管(MWNTs)分散到海藻酸钠(SA)水溶液中钙化制得复合凝胶球,对偶氮染料甲基橙进行吸附试验,研究了包埋不同含量MWNTs的凝胶球的吸附特点及最佳配比。试验结果表明:SA-Ca凝胶球对甲基橙去除率较低,当MWNTs的浓度为0.18%时凝胶球的吸附性能提高了近8倍;MO溶液的pH、电导率也发生了变化。

In this thesis, the author prepare SA-Ca and SA/ MWNTs-Ca by dispersing MWNTs into aqueous solution of SA to calcification and test their adsorption ability to methyl orange(the azo dye), in order to study the adsorption ability about SA-Ca with different content of MWNTs and the perfect mix of MWNTs. The experiment results show that the adsorption ability of SA-Ca to MO is low, but when the concentration of MWNTs is 0.18 percent, the adsorption ability is eight times higher than before and the pH values and electric conductivity of MO change as well.
