摘要
验证了柱前衍生高效液相色谱同时测定水性涂料中14种醛酮类化合物的方法。对本方法的检出限、精密度和稳定性进行了验证分析,并对水性涂料中醛酮类化合物的提取方法进行了优化。实验结果表明:本方法的检出限范围为0.002~0.08 mg/L,精密度范围为0.15%~6.87%,加标回收率范围为98.88%~102.17%。本方法在兼顾经济性的基础上,具有操作简单、峰分离效果好、检出限低、精密度和稳定性高、周期短的特点,适合同时测定水性涂料中14种醛酮类化合物。
The method for simultaneous determination of 14 aldehydes and ketones in waterborne coatings by Precolumn Derivatization high performance liquid chromatography was verified.The detection limit,precision and stability of this method were analyzed,and the extraction method of aldehydes and ketones in waterborne coatings was optimized.The experimental results show that the detection limit of this method is 0.002~0.08 mg/L,the precision is 0.15%~6.87%,and the recovery is 98.88%~102.17%.On the basis of economy,this method has the characteristics of simple operation,good peak separation effect,low detection limit,high precision and stability and short cycle.It is suitable for the simultaneous determination of 14 aldehydesand ketones in waterborne coatings.
