摘要
采用水热法制备了含有不同钒原子数的Keggin型磷钼钒杂多酸季铵盐PMo_(12-x)V_xO_(40)-TBAB(x=1~4,TBAB为四丁基溴化铵),选用大肠杆菌、金黄色葡萄球菌等4种菌种进行了抑菌性能测试。结果表明,合成的4种抗菌剂对大肠杆菌等菌种均有不同程度的抑菌效果,并且随着抗菌剂中钒原子数的增加,抑菌效果逐渐增强,是TBAB的1~2倍,其中PMo_8V_4O_(40)-TBAB对大肠杆菌的抑菌效果最好。
The Keggin type molybdovanadophosphoric heteropoly acid quaternary ammonium PMo12-xVxO40-TBAB （x = 1 - 4, TBAB was tetrabutyl ammonium bromide） were synthesized via the hydrothermal method. Antibacterial performance of Escherichia coil,Staphylococcus aureus and other strains were investigated. The results show that the four antimicrobial agents are armed with different bacteriostatic effects to Escherichia coil and other bacterium. With the increasing numbers of vanadium atoms in the agents,the antibacterial effects are improved gradually, which is one or two times of TBAB, in which the effect of PMos V4O40- TBAB to Escherichia coli is the best.
