本文研究了二氯胺与溴化钾的反应及其产物,采用微孔渗透膜分离-紫外分光测定系统,测定水溶液中的一氯胺与二氯胺。本法的线性范围为2×10~(-5)mol·l~(-1)—1×10~(-2)mol·l~(-1),标准偏差在2×10~(-4)mol·l~(-1)时为4.3％。
In this paper, the reaction of dichloramine with potassium bromide and its products were studied. The system of determination of monochloramine and dichloramine in aqueous solution was determined by using microporous membrane separation - UV spectrophotometry. The linear range of this method is 2 × 10 -5 mol·L -1 -1 × 10 -2 mol·L -1 with a standard deviation of 2 × 10 -4 ) mol·L -1 (4.3%).
