A cell consisting of three chambers was used for conducting this experiment, and each chamber was separated from the others with cation exchange membranes. The solution of calcium chloride was circulated in the chambers on both sides of the cell, while the solution of sodium chloride was filled in the central chamber. After a fixed time, measurement was conducted on the quantity of the calcium ions that transferred from the both-side chambers to the central one through the cation exchange membranes.
As a result, it was recognized that the increase in the concentration of the calcium chloride solution in the both-side chambers or the increase in the sodium chloride solution in the central chamber promoted the transferring rate of calcium ions through the cation exchange membranes. However, the rate was more remarkably affected by the concentration of sodium chloride solution than that of the calcium chloride solution, and it decreased when sodium chloride was added into the solution of calcium chloride.
In addition to the above, the effect of temperature on the transferring rate of calcium ions was also measured.
