摘要
在挥发酚(volatile phenolic compounds)的水质分析中,经常遇到空白值偏高,导致空白偏高的因素很多,比如:纯水的质量,试剂的纯度等,其中4-氨基安替比林的纯度严重影响空白值,通过苯洗和硅镁型吸附剂吸附两种方法提纯4-氨基安替比林来降低空白值。
In the water quality analysis of volatile phenolic compounds, people Often meet with blank value on the high side.There are Many factors that cause the blank on the high side, such as, the quality of pure water, the purity of reagents, etc.The purity of 4-AAP seriously affects the blank value. By benzene washing and silicon magnesium type adsorbent adsorption,we can purify 4-AAP to reduce the blank value.
