style="text-align:center;"> <img src="/Upload/thumb_5b4474330ba63_bateditor.jpg" width="450" height="338" alt="" /> </p> 　　1、要提高一水硫酸鎂原料的純度，購買或者制取高純度的原料。如果原料純度不高甚至含有雜質，那么成品的質量可想而知純度不會高。<br /> 　　2、其次在反應過程中不要混入其他的物質，包括氣體，防止氣體把反應過程中的物質氧化甚至發生其他反應。<br /> 　　3、然后是反應后根據需要進行過濾、提純等操作。以一水硫酸鎂為例，將工業一水硫酸鎂加入盛有80—90℃的熱蒸餾水槽中，邊加熱邊攪拌，溶解至質量濃度為1.21克/cm2用堿除去砷、重金屬等雜質，過濾后用活性炭脫色，濃縮至質量濃度為1.370g/cm2—1.384g/cm2,冷卻結晶，溫度達25—15℃時分離洗滌，在50—55℃下用振動流化床干燥，依據水質、除雜、脫色、洗滌程度的不同，得到不同等級的高純一水硫酸鎂。<br /> 　　總之，為了保證一水硫酸鎂的提純質量，我們需要嚴格按照規定的操作方法進行，以免在操作過程中出現雜質，影響產品后期的使用效率。<br /></div> <div class="page" style="clear:both;"> 上一條：沒有了<br> 下一條：<a
