摘　　要：以橙皮提取液作为还原剂制备纳米银,采用UV-vis探究的最佳工艺条件为温度70℃、加热时间40 min、提取液质量浓度25 g/L、硝酸银浓度3 mmol/L,采用XRD和SEM对纳米银进行了表征。结果表明,最适工艺条件制备的纳米银颗粒均匀,粒径在45~55 nm之间,近似为球形。Orange peel extract was used as a reducing agent to prepare nano-silver.The optimum process conditions were investigated by UV-vis at a temperature of 70℃,a heating time of 40 min,a mass concentration of 25 g/L in the extract and a concentration of 3 mmol/L in silver nitrate,the nanosilver was characterized by XRD and SEM.The results showed that the nanosilver particles prepared by the optimum process conditions were homogeneous,with particle sizes ranging from 45 to 55 nm and approximately spherical.
