摘要
目的建立硅酮二号凝胶中二甲硅油含量测定的红外分光光度法。方法采用红外分光光度计测定硅酮二号凝胶中二甲硅油含量,检测波数为1 262 cm-1。结果二甲硅油在0.409~2.863 mg/ml内,其吸收值与浓度呈良好线性关系,回归方程为：A=0.2193×C-0.004,r=0.999 9,回收率为100.13%,RSD为1.02%（n=6）。结论该方法简便快捷,准确度高,能满足硅酮二号凝胶中二甲硅油的测定。
Objective To establish a method to determinate dimeticone in type Ⅱ silicone gel by Infrared spectrophotometry.Methods The infrared spectrophotometry was adopted,and the detective wave was 1 262 cm-1.Results The linear range of the calibration of dimeticone was 0.409~2.863 mg/ml（r=0.999 9）,the average recovery was 100.13%,RSD=1.02%（n=6）.Conclusion The method was accurate,realizable which could be used to determinate dimeticone in type Ⅱ silicone gel.
