摘要
采用固相微萃取-气相色谱法测定生活污水中的壬基酚,优化了萃取纤维涂层材料、萃取时间与温度、解析时间与温度、盐度、pH值、搅拌速度等试验参数。方法在0.001 mg/L^1.00 mg/L范围内线性良好,检出限为0.000 6 mg/L,标准溶液平行测定的RSD为7.6%,生活污水加标回收率为42.7%~74.0%。
A method of gas chromatography with solid phase microextraction was applied for determination of nonylphenols in domestic sewerage. Test parameters were optimized such as fiber coating, extraction time and temperature, desorption time and temperature, salinity, pH as well as stirring speed to produce following results： good linearity in the range from 0.001 mg/L to 1.00 mg/L and the detective limits 0.0006 mg/L; The RSD of standard solution parallel samples 7.6%. The recoveries of domestic sewerage from 42.7% to 74.0%.
