摘要
针对焦化废水氨氮含量的快速测定方法进行了研究,采用美国哈希DR2700快速测定仪对水样中氨氮含量进行测定,同时将测定结果与纳氏试剂分光光度法测得的结果进行比较,结果表明:采用哈希快速测定仪测出的结果具有较好的精确度和准确度,同时该方法检出限大,操作简单,可以较好的应用于实际工业生产中。
The paper based on a fast analyzer and rapid determination of ammonia-nitrogen in co- king waste water, use the HACH DR2700 analyzer to determine the ammonia nitrogen content in water samples, and compared with the environmental standard Nessler spectrophotometry method obtain satisfactory results. The results show that： the HACH analyzer had features of wide linear range, it also maintained a good precision and accuracy in water samples containing high concentrations of ammonia-nitrogen.
