摘　　要：本文采用硅镁型吸附剂提纯4-氨基安替比林(4-AAP),通过不同提纯次数测定空白值、绘制校准曲线以及方法验证实验,得出采用硅镁型吸附剂提纯4-AAP 2次后测得的空白吸光值达到实验要求,其灵敏度和准确度高,方法检出限低于标准规定的要求。Based on the 4 - amino silicon magnesium adsorbent purification anti than Lin （4 - AAP）, through different purification number determination of blank value, method of calibration curve and the verification experiment, it is concluded that the silicon magnesium adsorbent after purification of 4 - AAP twice measured blank absorbance value meet the experimental requirements, its high sensitivity and accuracy, method detection limit is lower than the requirements of the standard.
