Discussion on the extraction of metal element Sc from the leaching solution of coal aluminum rock series clay rock
This article establishes an ion exchange method for separating and extracting metal element Sc from the leaching solution of coal aluminum rock series clay rock using self-made resin.The main focus is on exploring the effects of pH value and adsorption time on the adsorption of Sc by resin,and analyzing the mechanism and characterization of the adsorption using FTIR,SEM-EDX and other methods.The experimental results showed that when the pH value was 4 and adsorption time was 120 minutes,with 2M H2SO4 as the desorption solution and desorption for 1 hour,the recovery rate of Sc reached 78.15%to 80.12%,achieving the separation of Sc from other metal ions.
