用自制催化剂和氧化剂进行快速法测定CODcr结果 :1分析标样平均值接近真值。 2用国产 CODcr快速测定仪和 72 1分光光度计便可测到 1 0～ 1 0 0 0 mg/L CODcr。3在 COD浓度较低时曲线有很好的线性关系 ,使得降低快速法的定量下限成为可能。定量下限可达 9.0 7mg/L。 4与经典回流
Rapid determination of CODcr results with home-made catalysts and oxidants: 1. Analyze the standard samples to a near-true value. 2 with domestic CODcr rapid detector and 72 1 spectrophotometer can be measured 10 ~ 100 mg / L CODcr. 3 A good linearity of the curve at lower COD concentrations makes it possible to reduce the lower limit of quantitation of the fast method. Quantitative lower limit of up to 9.0 7mg / L. 4 with classic reflow
