Relative deviation analysis of organic compounds in the water

Through analyzing the monitoring data,the authors studied the relative deviation of 51 organic compounds in water,and put forward the quality control(QC) index under two kinds of probabilities(γ=0.90,P=0.90;γ=0.95,P=0.95) to provide the QC index for the people in the monitoring area.Studies indicate that the relative deviation of the actual samples and the recoveries of actual samples are higher than those of the blank samples.The relative deviation of the blank sample recovery could be controlled within 15%,which could be extended appropriately.The relative deviation of the actual samples and the actual sample recovery could be controlled within 20%.
