| 摘 要： | CODCr作为评价有机物污染的重要指标,在测定中氯离子是影响结果准确性的重要因素.研究了完全氧化法消除Cl-干扰的可行性,测定了K2Cr2O7浓度对Cl-对应CODCr的影响,绘制了完全氧化法的标准曲线;研究了ρ(Cl-)对水样CODCr结果的影响.结果表明完全氧化法适用于高氯废水中CODCr的测定.

| Abstract: | By COD_(Cr) as organic pollutants indexes,chlorine ion in aqueous-solution sample is the important interfering factor that can affect the accuracy of the determinative result.Based on the chemical experimentation the feasibility of eliminating the interference of chlorine ion was discussed by absolute oxidation,the COD_(Cr) responding to the chlorine ion in a series of samples containing different K_2Cr_2O_7 concentrations,and made the standard curve of absolutely oxidation,and deliberating COD_(Cr) in actual samples containing varied chlorine ion concentrations.Consequence has shown that absolute oxidation is fit in determining COD_(Cr) in the organic pollutant high-chlorine water. |
