Research on Determination Technology of Trace Mercury in Rainwater

摘要

In this paper, using Sulphydryl Cotton as solid absorptive enrichment agent of mercury, the best enrichment eluting method of mercury is confirmed by conditions trials in order to apply to the determination of mercury in rainwater in Guilin City. The practice proves that the adoption of this technology can simply concentrate the trace mercury in rainwater for scores of or even more than 100 times and can effectively enhance the precision of instruments detecting mercury.
