【摘要】 碳酸钙、碳酸氢钙及其混合水溶液分别以 3.7m/s的流速通过磁场强度为 60 4 0高斯的正交磁场进行循环运行。磁处理后碳酸钙水溶液的 p H值快速下降直至恒定 ,碳酸氢钙水溶液的 p H值先下降后上升出现一最低值 ,而混合水溶液的 p H值则缓慢下降 ,三种溶液的电导率均上升 ;室温放置 2 4 h后 p H值的变化趋势未变 ,但电导率变得相近 ,说明磁处理主要通过促进 CO2 的溶解而起作用的并具有“记忆效应”,这种作用与溶液的性质有关 ;溶液加热后的 p H值及电导率的变化也证明了这一点。更多还原

【Abstract】 Three water solutions were respectively circulated through an orthogonal permanent magnetic field with the intensity of 6040 gauss at a flow rate of 3.7m/s. The pH value of CaCO 3 solution rapidly decreased and then reached a constant; the pH value of Ca(HCO 3) 2 solution firstly decreased and then increased with a minimum value, but the pH value of CaCO 3 and Ca(HCO 3) 2 mixed solution slowly decreased; the room temperature, the pH value had the similar varying curves as that before to the cooling and the treated and untreated solutions almost had the same conductivity. These results showed that magnetic treatment increased CO 2 dissolving in the solutions and slightly affected the conductivity; in addition, the effect of magnetic treatment depended on the solution and the treated solution had the "magnetic memory effect". The results of heated solutions also approved this result.更多还原
