摘 要:建立了同时测定水基胶中异噻唑啉酮类杀菌剂和双酚A、壬基酚、辛基酚和邻苯二甲酸酯类环境激素的方法。样品经甲醇提取后,直接进超高效液相色谱-串联质谱(UPLC-MS/MS)分析,采用同位素内标法定量。研究结果表明:所有化合物在20~500 ng/mL浓度范围内线性关系良好(R^(2)≥0.9983),检出限(LOD)和定量限(LOQ)分别在0.009~0.115 mg/kg和0.029~0.382 mg/kg范围内;不同浓度水平下,所有待测物的回收率在84.1%~105.6%之间,日间相对标准偏差(RSD)小于8.0%;对60个实际样品进行检测,所有样品均检出异噻唑啉酮类杀菌剂,各有1个样品检出壬基酚和邻苯二甲酸二丁酯。本方法检测效率高,节约检测成本,尤其适合实验室大批量样品的日常检测。A method was developed for the simultaneous determination of isothiazolinone fungicides and environmental hormones such as bisphenol A,nonylphenol,octylphenol and phthalate in water-based adhesive.After methanol extraction,the sample was directly analyzed by ultra-high performance liquid chromatographytandem mass spectrometry(UPLC-MS/MS)and quantified by isotope internal standard method.The research results showed that all compounds showed good linearity(R^(2)≥0.9983)within the concentration range of 20~500 ng/mL,and the limit of detection(LOD)and limit of quantification(LOQ)were in the range of 0.009~0.115 mg/kg and0.029~0.382 mg/kg,respectively.At different concentration levels,the recovery rates of all analytes were in the range of 84.1%to 105.6%,the daytime relative standard deviation(RSD)was less than 8.0%.Sixty actual samples were tested,all samples detected isothiazolinone fungicides,and one sample each detected nonylphenol and dibutyl phthalate.This method had high detection efficiency and saved detection costs,especially suitable for routine detection of large batches of samples in the laboratory.
