摘　　要：确定了氯化铵是溶解水镁石较为合适的铵盐,考察了水镁石与氯化铵物质的量配比、反应温度以及反应时间等因素对水镁石溶解的影响。结果表明,在水镁石与氯化铵物质的量配比为1∶22、反应温度为100℃、反应时间为2 h的条件下,水镁石在氯化铵溶液中的溶解度最大,溶液中镁离子浓度达到了2.46%。It＇s identified that appropriate ammonium salt to dissolve the brucite was ammonium chloride. The effect of different factors on dissolving the brucite was investigated, such as ratio of ammonium chloride and brucite, reaction temperature and reaction time. The results show that： when the ratio of ammonium chloride and brucite is 1 ： 22, the reaction temperature is 100 ℃, the reaction time is 2 h, the solubility of the brucite in the ammonium chloride can reach the maximum, the ion concentration of magnesium is 2.46%.
