摘 要:氨法脱硫后的硫酸铵溶液的成分复杂,干扰物质较多,亚硝酸盐氮的含量较低。针对溶液的特点,本文采用紫外分光光度法测定此溶液中的硝酸盐氮和亚硝酸氮含量。实验结果表明,本方法操作简单,可快速准确地测定硝酸盐和亚硝酸盐中的氮含量,精密度和重现性较好,可用于在线测定。The ammonium sulfate solution after ammonia desulfurization had complex components,many interfering substances and low nitrite nitrogen content.According to the characteristics of the solution,ultraviolet spectrophotometry was used to determine the nitrate nitrogen and nitrite nitrogen in this solution.Experimental results showed that this method was simple operation and could be quickly and accurately analyzed the nitrogen content in nitrates and nitrites.The precision and reproducibility of this method were good,and could be used for online determination.
