Abstract

Abstract:

A new microwave-spectrophotometry process for determining chemical oxygen demand（COD_Cr） rapidly is put forward. Two methods for analyzing CODCr are compared. When compared with the standard method， it proves that microware-spectrophotometry method is characterized by water saving， time saving and simple operation and has better accuracy， precision and consistency

Key words: microwave, spectrophotometry, chemical oxygen demand

摘要：

介绍了一种微波-分光光度法快速测定COD_Cr的新方法,并与标准方法进行了比较。实验表明,微波-分光光度法具有比标准重铬酸钾法所需水样量小、节省时间、操作简单等优点,经与标准方法对照,其准确度和精密度一致性较好。
