| Abstract: | Total arsenic and inorganic arsenic in seaweed fertilizer were determined by atomic fluorescence spectrometry.HNO_3-H_2SO_4-HClO_4 was selected to digest the seaweed fertilizer for total arsenic determination.Inorganic arsenic was extracted by 50% HCl.The detection limit is 0.05μg/L, the recovery of total arsenic and inorganic arsenic are 89.8% and 86.8%, and relative standard deviation is 3.2%(n=11). |
