本文提出一种新的光度法——系数倍率导数分光光度法,用于邻氯苯亚甲基丙二腈和邻氯苯甲醛的测定,回收率分别为97.6～102.0％和97.5～104.2％。实验结果表明方法快速、准确、可靠。
In this paper, a new luminosity method - coefficient multiples derivative spectrophotometry was proposed for the determination of o-chlorobenzalmethandronitrile and o-chlorobenzaldehyde. The recovery rates were 97.6 ~ 102.0% and 97.5 ~ 104.2%, respectively. The experimental results show that the method is fast, accurate and reliable.
