摘要
本文采用智能一体化COD消解仪,通过测定方法的检出限、测定下限、精密度和准确度,验证了该仪器在高氯废水COD测定中的可行性.实验结果表明:该仪器测定高氯废水COD检出限小于10mg/L,精密度相对标准偏差范围为1.3％～6.7％,准确度相对误差在-4.1％～2.5％,显示出较高的精密度和准确度,均符合标准(HJ/T 70-2001)的要求,并且操作简便.
Abstract
The present study utilizes an intelligent integrated COD digestion instrument to assess the feasibility of measuring COD in high-chloride wastewater.This assessment is based on the detection limit,lower limit of quantification,precision,and accuracy of the measurement method.The experimental results indicate that the detection limit is less than 10 mg/L,with a relative standard deviation for precision ranging from 1.3％to 6.7％,and a relative error for accuracy between-4.1％and 2.5％.Both precision and accuracy demonstrate relatively high levels.The measurements obtained using the intelligent integrated COD digestion instrument meet the standards set forth in HJ/T70-2001 regarding precision and accuracy for determining COD in high-chloride wastewater.Furthermore,this instrument offers ease of operation.
