卤水中钾和镁的利用

Abstract

Abstract: Many ions such as Na⁺,K⁺,Mg²⁺ ,Ca²⁺ ,Li⁺,SO^2-₄,and Cl^- are contained in brine, in which K⁺ and Mg²⁺are important materials to produce potassium and magnesium products.Besides,proper utilization of brine will ease environmental problems caused by direct discharge of it.Focusing on utilization of brine resources,research progress in preparation of potassium and magnesium products using brine as raw material were introduced emphatically.After comparison and analysis,the technical features and development trends of preparation of potassium and magnesium products with brine as raw material were summarized.Then,current situation and problems of utilization of brine resources were briefly analyzed. 

Key words: brine, potassium;magnesium

CLC Number:

TQ131.13
