摘要
对传统吡啶-碱目视比色法进行了改进,并将其应用到磷肥中三氯乙醛的检测中,结果表明吡啶-碱-联苯胺-甲酸分光光度法显色稳定,测定精度高,准确度好,可用于磷肥中三氯乙醛的测定。
The traditional pyridine-alkali visual colorimeyry has been improved in this paper,and it is used in the determination of trace trichloroacetaldehyde in phosphate fertilizer.The results show that pyridine-alkali-benzidine-formic acid spectrophotometry is stable for color and high precision and accuracy.This method can be used for the determination of phosphate in the chloral.
