Abnormal behaviors of copper (II) and zinc ions in parent solution at the early stage of calcite formation

抄録

The behaviors of copper (II) ions and zinc ions in calcium bicarbonate parent solution at the formation of calcite and the influence of fluoride ions on them have been studied through the measurement of the distribution coefficients of copper and zinc between calcium bicarbonate parent solution and calcite precipitated in the solution. The distribution coefficients of copper and zinc were measured to be abnormal at the early stage of calcite formation but constant at the late stage. Their abnormal behaviors at the early stage of calcite formation are shown and discussed in this paper.
