Abstract
On the basis of a large number of monitoring data from many laboratories nationwidely,studied the quality control index of the As and compared with the QC index inmonitoring method of water and wastewater.The purpose of which was to provide an QC index for the people in the monitoring area.Studies indicate that the RSD(within-laboratory relative standard deviation)control limit of standard samples was less than 4.0%,relative deviation of actual samples which concentration below 0.05 mg/L was less than 10%,and the concentration above 0.05 mg/L was less than 5%.RSD′(inter-laboratory relative standard deviation)was less than 10%.The relative error of the standard samples was controded within ±15%.The correspounding recovery rates can be ranged between 90% and 110%.
