Abstract: The distribution behavior of manganese with calcium carbonate, calcite and aragonite was studied at 25°C.Precipitates of calcite and aragonite were made from calcium bicarbonate solution by the homogeneous precipitation method.Five point seven was obtained as the logalithmic distribution coefficient of manganese with calcite, and 0.058 was obtained as that of manganese with aragonite.The reason why the distribution coefficient of manganese with calcite is about one hundred times as large as that with aragonite is considered to be the distortion energy in the aragonite crystals which comes from the difference of free energy of ideal solid solution and that of real solid solution.
