摘要
通过实验,对制浆造纸废水氨氮采用纳氏试剂分光光度法分析(絮凝沉淀、预蒸馏)[1]检测结果进行比较,得出了絮凝沉淀、预蒸馏检测结果差异较大,主要原因是制浆废水色度、浊度较高影响,得出对此类样本采用预蒸馏前处理检测结果准确可靠。
Through the experiment,the ammonia nitrogen in pulping and papermaking wastewater was analyzed by Nessler's reagent spectrophotometry(flocculation sedimentation,pre-distillation),and the test results were compared.It was found that the difference between flocculation sedimentation and pre-distillation was large,mainly because of the high influence of the chroma and turbidity of pulping and papermaking wastewater.It was concluded that the test results of pre distillation treatment of such samples were accurate and reliable.
