一种杂多酸多氮化合物的合成及性质研究

Synthesis and Properties Study of A New Multi-nitrogen Compound Containing Heteropolyacid

以有机配体1,4-二(1,2,4-三唑-1-甲基)苯、磷钼酸为原料,采用水热法合成了一种杂多酸多氮化合物1。通过x-单晶衍射测定了化合物的结构。研究了该化合物对染料亚甲基蓝的吸附作用,当亚甲基蓝的浓度为5 mg/L时,25 mg化合物的平衡吸附容量qe为4.88 mg/g,去除率达到98%,吸附的动力学研究表明为二级动力学,吸附机理为henry型吸附模型。

A multi-nitrogen compound 1 containing heteropolyacid was synthesized with phosphomolybdate and 1,4-bis（1,2,4-triazol-1-ylmethyl） benzene as raw material by hydro-thermal method. The structure of compound 1 was characterized by X-ray signal crystral. Compound 1 has good adsorption effect to dye methylene blue. The equilibrium adsorption capacity （qe） of 25 mg compound 1 was 4.88 mg/g, and the removal rate was reach to 98 % when the concertration of methylene blue was 5 mg/L. The adsorption kinetic study shows that the behaviour was secondary dynamics, and the adsorption mechanism was consistent with henry adsorption model.
