| Abstract: | Bromine, iodine, arsenic and selenium was determined by ICP-MS with sample pretreatment using semi-molten flux, water extraction and removing most cation using strong-acid cation exchange resin. Relative deviation is less than 6.9% of sample analysis by comparing muhi-objective recommended analysis method. The detection limit, precision, accuracy test of the method meet the requirements of the code by determined 12 national standard reference materials. |
