More Information
Summary:The invention discloses a method for improving the transparency and reducing the turbidity of sodium alginate produced by a calcification method. A chelation process is added between a decalcification process and a squeezing process in the production of the sodium alginate; in the chelating process, calcium ions in alginic acid at the discharging end of the decalcification process are chelated and settled by using a chelating agent; according to the scheme, the transparency of sodium alginate can be effectively improved, the turbidity is reduced, and the performance of a sodium alginate product is improved. 本发明公开了一种提高钙化法生产海藻酸钠透明度和降低浊度的方法，在海藻酸钠生产中的脱钙工序和压榨工序间增加螯合工序；在螯合工序中，使用鳌合剂对脱钙工序出料端的海藻酸中的钙离子进行鳌合沉降；该方案可有效提升海藻酸钠透明度、降低浊度，提升海藻酸钠产品性能。
