摘要 在酸性溶液中以二苯碳酰二肼(DPC)作为显色剂测定总铬,高锰酸钾作为氧化剂时,操作过程繁琐。改用过硫酸铵代替高锰酸钾作为氧化剂,不仅操作简便、快速,而且分析效果良好,结果可靠。 It is complex to determine total chrome with DPC as streak reagents and potassum permanganate as oxidant.We use ammonium persulfate as oxidant instead of potassum permanganate.It's quick and easy to operate,and the result is reliable.
