通过对大量监测数据进行统计分析，获得异烟酸-吡唑啉酮光度法（HJ484—2009）测定水中氰化物质量控制评定指标。研究表明：样品浓度在0．05～0．3mg／L范围内时，建议控制室内相对标准偏差≤3％，室间相对标准偏差≤10％；样品浓度小于等于0．05mg／L时，建议控制相对偏差≤10％；样品浓度大于0．05mg／L时，建议控制相对偏差≤5％；在0．05—0．3mg／L浓度范围内，重复性在0．002-0．014mg／L之间，再现性在0．008—0．614mg／L之间；在0．04-0．50mg／L浓度范围内，建议控制相对误差在±20％范国内；加标回收率范围为90％-110％。

Based on statistics and analysis of a lot of data, quality control index for determination of cyanide in surface water by Isonicotinic acid-pyrazolone spectrophotometric method （HJ484 -2009） was obtained. The study showed that when the sample concentration was from 0. 05 to 0. 3mg/L, it was suggested to control the in lab relative standard deviation ≤3% and the inter-lab relative standard deviation,≤ 10% ; when concentration was lower than 0. 05mg/L, controlling the relative deviation 10% ; when concentration was higher than 0. 05mg/L, controlling the relative deviations〈5% ; in the range of 0. 05 -0. 3mg/L, the repeatability and reproducibility were in the range of 0. 002- 0. 014 mg/L and 0. 008 - 0. 614mg/L respectively; in the range of 0, 04 -0. 50 mg/L, controlling the relative error within ±20% ; the spiking recoveries were from 90% to 110%.
