摘　　要：采用液相离子交换法,将抗菌铜离子与钠基蒙脱石合成抗菌层状硅酸盐材料。研究了溶液浓度、pH值及反应时间等对合成抗菌材料中铜离子含量的影响。通过正交试验确定合成铜型抗菌层状硅酸盐的较佳反应条件为:CuCl2溶液的浓度0 1mol·L-1,在自然pH值下反应约1h。实验还测定抗菌层状硅酸盐的抗菌性能:铜型抗菌层状硅酸盐抗大肠杆菌、金黄色葡萄球菌等细菌性能良好,但抗霉菌性能一般。The antibacterial layer silicate was synthesized by liquid-phase ion exchange fixing bactericidal metal ion Cu2+ on Na-montmorillonites. The effects of concentration, pH value, and reacting time on antibacterial ion content were studied. The optimum conditions of the synthesis was determined by the orthogonal test and stated as follows. They are 0.1 mol·L-1 of the concentration of CuCl2 , 1 h of reaction time and with natural pH value. The antibacterial capability of synthesized layer-silicate was also tested. The antibacterial property of Cu-antibacterial layer-silicate against bacteria such as Escherichia coli and S.sauceus was better than that of mould .
