| Abstract: | The effects of many kinds of coat metals and modifier on determining Be in water were investigated, and the method, which uses modifier （NH4）2H2 PO4 and graphite tube with La coated to determine Be in water, was established. In this method, the lowest detection limit is 0. 037 μg/L, the relevant precision is 7.4%, and the recovery ratio is 98%～106%. |
