Abstract: By means of dathizone spectrophotometriec analysis method ,the trace Hg2+ in the high calcium intensification agentswere determined,the results showed that the sensitivety and recovery rates were high and the relative error small and theeffects good,the results were compared with mercury measurer method and rather approach to it.

Key words: high calcium intensification agenfs, dathizone, spectrophotomietry
