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。 Heteropoly acid poly-nitrogen compound 1 was synthesized by hydrothermal method using organic ligand 1,4-bis (1,2,4-triazole-1-methyl) benzene and phosphomolybdic acid as starting materials. The structure of the compound was determined by x-single crystal diffraction. The adsorption of methylene blue by the compound was studied. When the concentration of methylene blue was 5 mg / L, the equilibrium adsorption capacity of 25 mg qe was 4.88 mg / g and the removal rate was 98%. The kinetics of adsorption was shown as Class dynamics, adsorption mechanism for the henry-type adsorption model.
