Abstract: The method for determination of trace arsenic in activated casbon using the hydride generator and by atomic absorption spectrometry was established. The principle of test was introduced. The influenced factors to test results were discussed. The changes of arsenic contents and strength of three kinds of activated carbon were observed and compared each other.

Key words: hydride, atomic absorption spectrometry, determination of arsenic
