摘要
本文研究了使用间隔流动分析仪测定水中的六价铬的方法,与GB/T 7467-1987水质六价铬的测定中的二苯碳酰二肼分光光度法进行对照试验,结果令人满意。本方法出去了很繁琐的前处理离心工作,方法简单,大大提高了检测的效率,缩短了时间,还具有精密度较好的特点。本方法适用于测定饮用水、地表水、生活污水以及工业废水中六价铬。
This paper studies the use of interval to measure the water flow analysis method of hexavalent chromium, and GB / T 7467-1987 Determination of hexavalent chromium in the water quality of the two diphenyl carbonyl hydrazine spectrophotometer controlled trials with satisfactory results. The method is very tedious to go out pre-processing centrifuge work, method is simple and has greatly enhanced the efficiency of detection and shorten the time, also has a precision of better features. This method is applicable to determination of drinking water, surface water, domestic sewage and industrial waste water hexavalent chromium.
