摘要
将分光光度法应用于硝基苯生产过程中碱性废水中硝基酚类含量的测定,在碱性条件下(pH>9),波长360nm处测定其硝基酚类的含量。该方法操作简单,灵敏度高。
Spectrophotometry is applied to monitor the content of mononitrophenol ( alkalinity: ph 〉 9, wave length:360nm ), which exists in alkali waste water from nitrobenzene production. The method is simple, high sensitivity.
