摘要
借助析晶动力学监测系统 ,研究了一定强度的磁场对碳酸钙过饱和溶液的析晶过程的影响。定量的、可重复的数据表明 ,在一定的Ca2 + 和CO3 2 -浓度范围内 ,磁场对碳酸钙晶体的生长析出具有明显的抑制作用。对不同溶液进行磁处理的实验结果显示 ,磁场阻垢既通过成垢阳离子Ca2 + 起作用 ,也通过成垢阴离子CO3 2 -起作用。
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.
