摘要
建立了用高效液相色谱法测定硝基涂料中的邻苯二甲酸酯类化合物的方法。样品待挥发性有机物挥发后,用乙醇提取其中的邻苯二甲酸酯类,直接用HPLC分析,外标法定量。该方法的精密度为2 05%～4 93%,回收率为79 5%～106 0%,检出限为DMP0 14ng,DEP0 22ng,DBP0.61ng。
A method for the determination of phthalates in coatings by HPLC was established. The coatings were extracted with ethanol after some benzene, toluene and xylene had volatilized, then the upper clear layer was injected into HPLC for detection at λ=275 nm. Quantitative analysis was performed with external standard method. A relative standard deviations was 2.05%～4.93% and a recovery range of 79.46%～106.04% were obtained. The detection limits were 0.14 ng for DMP, 0.22 ng for DEP, 0.61 ng for DBP.
