摘　　要：考察银离子浓度、pH、温度、时间等制备条件对油茶果壳载银抗菌剂性能的影响,并考察了材料对大肠杆菌、金黄色葡萄球菌的抑制效果。结果表明:油茶果壳载银抗菌剂的最佳制备条件为吸附时间6 h,搅拌温度35℃,pH=4,银离子浓度是0.2 mol/L,制备的油茶果壳载银抗菌剂对大肠杆菌、金黄色葡萄球菌具有优异的抗菌性能。Camellia oleifera abel shells carrying Ag was prepared on the different conditions of silver ion concentrations, pH, adsorption time and temperature. E. coli and S. aureus was used to evaluate the antibacterial activity of Camellia oleifera abel shells carrying Ag. The results showed that the optimum preparing conditions were which adsorption time was 6 hours, temperature was 308 K, pH was 4 and silver ion concentrations was 0.2 mol/L. The Camellia oleifera abel shells carrying Ag had significant antibacterial activity against E. coli and S aureus.
