摘要
Abstract
The saturated potassium sulfate is added in the electrolyte leading to the formation of pre-cipitation of silicon fluoride acid and lead separated from other elements.After the silicon fluoride acid was titrated with sodium hydroxide solution,the lead was tritrated with EDTA.The recovery rate of the silicon is 97.9% to 101.3%,the recovery of lead is 97% to 102.07%,the method is simple,accurate and fast,and can meet the requirements of production.关键词
