摘要
应用便携式CODcr分析仪平行多次测试长江水源水、城镇污水厂出口废水、钢铁炼焦废水和石化企业污染源废水4种监控区域的水环境应急监测CODcr样品,将其结果与国标方法《水质化学需氧量的测定重铬酸盐法》(GB11914-89)的测试结果进行比较并对CODcr有证标准样品进行同步测试,综合运用F检验、t检验统计方法证实便携式CODcr分析仪满足水环境应急监测中CODcr测试的精密度和准确度要求,在提高分析效率、降低试剂消耗方面优势显著,具有良好的应用推广价值。
6 parallel tests were carried out for each water sample which were from the Yangtze River water, urban sewage treatment plant, steel coking wastewater and petrochemical pollution emergency pool respectively,using a portable CODcr analyzer. The test results were compared with the national standard method Water quality-Determination of the chemical oxygen demand-Dichromate method （GBl1914-89）,and the certified reference materials were synchronously tested for verification. The statistical results of F test and t test method showed that the precision and accuracy of the portable CODer analyzer could meet the test requirements. Portable CODer analyzer can be used for water environmental emergency monitoring.
