摘　　要：在水环境检测方法中存在绘制校准曲线和样品的测定过程存在差异的情况。文章以氰化物的测定为例,利用测定率校正由此产生的系统误差,提高检测结果的准确性。结果表明:通过HJ484-2009分光光度法进行水中氰化物测定时,测定率还原法是一种有效的改进方法,经还原后,检测的准确度得到有效提高。There are differences in the process of drawing calibration curve and sample determination in water environment detection methods.Taking the determination of cyanide as an example,this paper shows the process of correcting the resulting systematic error by using the determination rate to improve the accuracy of the detection result.The results show that the rate reduction method is effective for the determination of cyanide in water by HJ484-2009spectrophotometry,and the accuracy of the detection is effectively improved after reduction.
