| titleOfInvention | Method for direct separation of arsenic from arsenic-containing solutions |
| abstract | The invention discloses a method for directly separating arsenic from an arsenic-containing solution, which comprises the steps of adsorbing the arsenic-containing solution through an adsorption resin to obtain a dearsenic solution. The adsorption resin is a strongly basic anion exchange tree. The adsorption resin is eluted by deliquoring to obtain an arsenic-containing elution waste liquid, wherein a specific sampling volume is used for both adsorption and elution, and the arsenic-containing elution waste liquid is vulcanized, and the ORP of the redox potential is controlled to be ‑100 mV～100 mV, Arsenic sulfide slag and post-sulfide liquid are obtained. The method of the invention is mainly aimed at separating arsenic from aqueous solution or acid solution containing arsenic, and can only directly remove arsenic, can open more than 95% of arsenic, avoid the loss of other components such as valuable metals and acids, and has a simple process , the processing cost is low. |
