| Abstract: | Using a homemade device of the electric heated quartz-tube atomizer,including a con-trolling temperature unit and a continue hydride generator,trace mercury in samples of "liuWei Di Huang Wan"has been determined directly. The method is simple,convenient, and ofgood precision and high accuracy. It is a very practical method for the analysis of trace mer-cury- The determination limit is below O. 1ppb,and the recovery is 90- 98%' |
