摘要
使用DRB200数字式消解器、DR/2400便携式分光光度计,测定水中化学需氧量,不同的消解时间对测定值的影响,用COD标准溶液对实际样品的测定进行校核试验,其精密度、准确度和加标回收效果理想。
Chemical oxygen demand was determinated by DRB/200 digital devices and DR/2400 portable spectrophotometer.Impact of different digestion time on the determination value was studied.The determination of the actual sample was checked by COD standard solution.The results showed that precision,accuracy and recovery rate were satisfactory.
