摘要
针对目前国内较少研究磷酸铵镁在各种环境条件下的溶解度变化情况,探讨了磷酸铵镁条件溶度积的主要影响因素。结果表明,pH对磷酸铵镁条件溶度积影响显著,温度、盐度、有机物和有机酸含量等仅在一定范围内对磷酸铵镁条件溶度积产生明显影响。基于技术经济可行性,建议磷酸铵镁结晶法的pH为8.5。
Since there was little research on the solubility of MAP in various environmental conditions in China, the main influence factors of equilibrium conditional solubility on product of MAP were discussed here. The results showed that the influence ofpH was remarkable, while that of temperature, salinity, content of organic compound and organic acid was obvious only in a certain range. Considering the feasibility of technology and economy, it was suggested that the best pH for MAP crystallization process was 8.5.
