摘要
通过建立液相色谱外标法来测定水性涂料中游离甲醛的含量。线性相关系数为0.99994,平均回收率为97.8%~101.6%,相对标准偏差为1.2%。该方法具有简便、快速、准确等优点,适用于水性涂料中游离甲醛含量的测定。
The free formaldehyde content in waterborne coatings was measured by establishment of liquid chromatography external standard method. The results showed that the linear correlation coefficient was 0.999 94, the average recovery rate was 97.8%-101.6%, and the RSD was 1.2%. The method is simple, rapid and accurate, and it is suitable for the determination of free formaldehyde in waterborne coatings.
