摘    要:根据丁基黄原酸具有在301 nm紫外波长段有最大吸收峰,pH<2时1 min内能够完全被分解,同时该吸收峰消失的特性,采用紫外分光光度(UV)法测定待测水样中丁基黄原酸浓度,并用待测水样作为背景校正,可有效地消除干扰.该方法的检出限为0.006 mg/L、测定上限为12.00 mg/L,实际水样测定的相对标准偏差小于5.76%.利用不同方法对样品进行分析测试,无明显差异.该方法具有线性相关性好、线性范围宽、操作简单准确等特点.

Abstract:A simple analytical method, using an UV spectrophotometer, for measurement of butyl xanthate in filtered water sample is reported. The method was developed based on the fact that a water containing butyle xanthate will lose the characteristic peak at 301 nm of its UV spectra at a pH<2 as a result of the rapid decomposition of butyle xanthate. Using the same water sample for background correction removed the interfering effect of other constituents. The method was successfully employed in measuring butyle xanthate in many water samples with a standard deviation of less than 5.76%. With a detection limit of 0.006 mg/L, this is an attractive method for detection and measurement of up to 12.00 mg/L of butyl xanthate in a water sample.
Keywords:Butyl xanthate Determination UV spectrophotometric measurement
