摘要
利用分光光度法、微波密封消解法测定水样中的化学需氧量 ,并把测定的精密度、准确度与国标回流法相比较 ,结果证明 :分光光度法、微波消解法是测定化学需氧量的快捷方法 ,具有省时、省试剂。
Spectrophotometry and microwave sealed digestion methods were adopted to determine the COD in the water sample. After comparing their precision and accuracy with national standard reflux method, we get the result which showed that spectrophotometry and microwave sealed digestion methods are rapid methods to determine the COD with less time, less dose and high efficiency.
