The effect of the magnetic field with certain strength on the precipitation of supersaturated calcium carbonate aqueous solutions is investigated by using Dynamic Precipitation Measurement System (DPMS). Quantitive and reproduceable data implied that the precipitation of calcium carbonate is obviously suppressed when the concentrations of calcium cation and carbonate anion are appropriate. The kinetics of precipitation of calcium carbonate solutions implied that the magnetic effect were attributable both to the magnetic treatment on sodium carbonate solutions and to that on calcium chloride solutions.
Key words： magnetic treatment; calcium carbonate; kinetics of precipitation
