摘要
在盐酸羟胺还原体系中萃取，用铜试剂将丁基黄原酸亚铜转化成铜试剂亚铜，进而分光测定丁基黄原酸的新方法．大大提高了比色法的灵敏度，其浓度在０～８０μｇ／Ｌ符合比耳定律，相对误差小于１．５％，平均回收率达９２％～１０５％，适用于水中丁基黄原酸的测定．
Coppe n-butyl xanthane is turned into copper sodium diethyldithiocarbamate in the reducing condition of hydroxylamine hydrochloride,and then ,n-butyl xanthahe is determined by spectrophotometry. In this case, the spectrophotomtric sensitivity is obviously developed with the concentration of 0- 80ug/L, Berr's Law being tallied, the relative error below 1. 5% and the recovery ratio of 92-105%. This method is useful in the determination of n-butyl xanthane in water.
