  1. aMeasured by the method in this work. bMeasured by the referring AFS mass method. cconfirmed by independent analysis using the AFS mass method. Recovery ratio was measured by the ratio of total arsenic concentration measured by fluorescence method to that measured by AFS. RSD (%): relative standard deviation, showing the solution is tested repeatedly for 3 times, reflecting the precision of the test results with n = 3.
