珍珠岩表面改性及对2，4-二硝基苯肼的吸附研究

Study on Adsorbing 2,4-Dinitrophenylhydrazine by Surface Modified Perlite

以珍珠岩尾砂为基体,用硅烷偶联剂对其表面进行改性。X-衍射结果表明:改性后珍珠岩表面与偶联剂发生了化学键合,从而实现了其表面的改性。用改性后的珍珠岩对2,4-二硝基苯肼进行吸附实验,结果表明:改性后珍珠岩对2,4-二硝基苯肼的吸附明显优于珍珠岩尾砂,去除率可达80%以上。

With the perlite ore tailings as matrix, surface modification of perilite with silane coupling agents was carried out. XRD showed that the perlite was modified by silence coupling agents compounded with surface of perlite. The adsorption test of the surface modified perlite for 2,4-dinitrophenythydrazine was carried out. The research results indicated that the adsorption effect was obviously superior to the perlite tailings, the removal rate could reach above 80%.
