摘要：

Using dithizone as a precolumn derivatization reagent, four species of Hg were quantitatively separated and determined by RP-HPLC. The method described has high analytical sensitivity, it can be applied for speciation analysis of Hg in natural water. The retention mechanism of Hg-Dz chelates was also investigated.
