摘要
本文报导了以废物鸡蛋为原料用盐酸浸溶,然后加硫酸制取硫酸钙的方法,采用L9(3^4)正交实验获得了从鸡蛋壳制取硫酸钙的最佳条件,其工艺简单,产品质量稳定,为废物的综合利用开辟了一条新途径。
Using waste egg shells as raw materials,hydrochloric acid(HC1) soaking and sulfuric acid(H2SO4) adding,the calcium slfate' s product technique is reported. The optimun technique conditions are obtained by L4(3+) orthogonal test method. The making technique is simple,and the product quality stable,Here is a new way of utilizing waste materials.
