An experiment simulating natural acidity of rainfall was conducted for eluviations of the vanadium-bearing stone coal of Lower Cambrian Hetang Formation of western Zhejiang Province at different pH values in the three components (3.5, 5.5 and 7.5). The concentrations of heavy metals in filtrate were measured using inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma optical emission spectrometer (ICP-OES) to study the release of Cd, and Pb at different acidity-alkalinity. The results showed that the concentrations of Cd in filtrate were inversely proportional to the pH value of leachate, and the leaching rates of Cd and Pb were 10.41% and 0.07%, respectively.
