摘　　要：本文针对《液体盐》(QB/T 1879-2020)中精制液体盐对硅指标要求的提高,提出采用铁盐混凝沉淀法进行深度除硅,并对铁盐添加量、反应时间、pH值等参数进行了研究,得出上述参数的最佳控制范围,为精制液体盐生产提供理论依据。In order to improve the requirements of refined liquid salt on silicon index in Liquid Salt(QB/T 1879-2020),this paper proposes to adopt the coagulation precipitation method of iron salt for deep silicon removal,and studies the parameters such as the addition amount of iron salt,reaction time and pH value,and obtains the best control range of these parameters,which provides a theoretical basis for the production of refined liquid salt.
