摘　　要：Objective To establish a method for preparing urine arsenic quality control samples and verify its uniformity and stability.Methods Urine samples of healthy adults were collected,concentrated and then freezedried using a freeze dryer.The freeze-dried samples were subjected to atomic fluorescence spectrophotometry to determine the arsenic content.The method was verified from the uniformity,stability,determination of different detection methods,and the fixed value of urine arsenic content.Results The linear correlation coefficient of the standard curve of the method was 0.9997.

关 键 词：stability. ARSENIC STABILITY
