| Abstract: | 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%. |
