摘　　要：对催化快速法和标准回流法测定废水中COD作了对比研究,即在对催化快速法进行空白实验及检出限的计算、校准曲线及其精度分析、方法精密度及其方差分析和方法准确及其误差分析等项验证工作的基础上,与标准回流法进行了实际样品的对照实验.结果表明,与标准回流法相比,催化快速法具有快速、简便的优点.Comparative study on the determination of COD in wastewater by catalytic rapid method and standard reflux method were engaged in,following conducted comparative:blank test and limit of detection,calibration curve and its precision analysis,the precision and its standard deviation,the accuracy and its error,balance experiment of real example.It showed,compared with standard reflux method,catalytic rapid method is simple and rapid,and they are comparable.
