摘要
应用分光光度法测定废水中CNS^-离子,文献已经指出Cr^(6+)、还原剂、有机物对测定结果有明显影响。经过我们的观察与实验发现还有其它因素,如使用液浓度、反应时间、Cl^-离子干扰。这些对CNS^-离子测定也起着重要影响。
The determination of CNS^- in wastewater with spectrophotometric method was discussed. According to references, Cr^(6+)、reduetant and organic matter had evident influences on the CNS^- determination. Through experiments, we found that some other factors, including Cl^-、concentration of standard sample and reaction time, have substatial effect on interfering CNS^- determinations.
