Authors have been summarized the research progress on heavy metals partitioning in carbonate calcium formation. The review is divided two parts. The topic for the part 1 is theoretic background and experimental methods. The topic for the part 2 is research progress and partitioning mechanism. Here is the part 2. In this paper, the advanced experiments related to sorption selectivity of heavy metal ions on calcite surface have been summarized. The results for observation of mono-molecular step distribution on the calcite surface by an atomic force microscope (AFM) were introduced. The theoretic mechanism on heavy metal ions partitioning problem, such as: Two Step Model, Multiple Surface Sites Model, Surface Film Model and Chemisorption Model etc. Has been reviewed. The proposal for future work has been presented.
