以磷钼酸、有机配体1,4-二(1,2,4-三唑-1-甲基)苯为原料,采用水热法合成了一种新的杂多酸多氮化合物1。通过x-单晶衍射测定了化合物的结构,研究了该化合物的热稳定性,以及在常温下该化合物对染料罗丹明B的吸附作用,当罗丹明B的浓度为5mg/L时,25mg化合物的平衡吸附容量q_e为9.65mg/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 new heteropoly acid poly-nitrogen compound 1 was synthesized by hydrothermal method using phosphomolybdic acid and organic ligand 1,4-bis (1,2,4-triazol-1-yl) benzene as raw materials. The structure of the compound was determined by x-single crystal diffraction. The thermal stability of the compound and the adsorption of rhodamine B at room temperature were studied. When the concentration of rhodamine B was 5 mg / L, 25 mg of compound The equilibrium adsorption capacity q_e was 9.65mg / g, the removal rate reached 98%. The kinetics of adsorption showed second order kinetics. The adsorption mechanism was henry adsorption model.
