Technological Research on Extraction Separation of Rubidium and Potassium in High-salt Waste Liquid and Preparation of Rubidium Chloride AITranslate
Abstract AITranslate
In order to recover rubidium and potassium from a high-salt wastewater in Jiangxi, t-BAMBP was used as the extractant and sulfonated kerosene was used as the diluent to separate rubidium and potassium.The effects of feed solution pH,extractant concentration, extraction phase ratio, extraction time and extraction stage on the extraction rate of rubidium and potassium, and the effects of washing phase ratio and washing stage on the elution rate of rubidium and potassium were investigated.The results show that the extraction rate of rubidium reaches 98.42% by 10-stage extraction under the conditions of feed solution pH 13.5,extractant concentration 0.8 mol/L,O/A phase ratio 5∶1,and extraction time 5 min.Finally, rubi-dium chloride product with a purity of more than 99% is obtained by evaporation and crystallization.
