摘要
目的研究消毒剂中有效成分——对氯间二甲苯酚、三氯羟基二苯醚的测定方法。方法选用高效液相色谱法,以乙腈∶水=60∶40(用冰醋酸调pH值3.0)为流动相,选用二极管阵列检测器,检测波长为280nm。结果对氯间二甲苯酚和三氯羟基二苯醚检出限分别为2.48、2.08ng,平均回收率范围为95.4%～103.3%,相对标准偏差为0.6%～3.4%。结论高效液相色谱测定法准确度和精密度较高,适用于含对氯间二甲苯酚、三氯羟基二苯醚消毒剂样品的测定。
Objective To study the method for determination of nipacide PX and triclosan in disinfectant by high performance liquid chromatography. Methods High performance liquid chromatography, based on the mobile phase (CH3CN:H2O=60:40, pH=3.0) and diode array detector(DAD, λ= 280 nm), was chosed to determine nipacide PX and triclosan in disinfectant. Results The detection limit of nipacide PX was 2.48 ng and triclosan was 2.08 ng. The rate of recovery was 95.4%-103.3%,the relative standard deviations(RSD) was 0.6%-3.4%. Conclusion The method is simple, precise and suitable for the determination of nipacide PX and triclosan in disinfectant.
