摘要
运用微波消解法和国标回流法分别测定不同浓度同一标准水样的COD,运用数据分析中的基本偏差分析与T检验法,通过多项式拟合的手段,确立了表述两种方法测定结果的定量方程,为分析水样的COD提供了快速简便的新方法。
Microwave digestion technology and standard method were used to determine standard solutions with various COD concentrations. On the basis of basic analysis of deviation and T-test, the relative equations of the results between two measures were expressed by using method of polynomial fit, which provided a quick, simple and new method for COD determination.
