Ion palladium solution chemical reduction method

     

Ion palladium solution chemical reduction method: Production line wastewater containing ion-balanced palladium acid is collected through dedicated pipes and introduced into the original water storage tank. Acid and alkali wastes should be separated. After pumping with a water pump, the liquid is adjusted to a certain pH value in the regulation pool. Then, it is drawn into the reaction pool, where a specific palladium fluoride reagent is added slowly to precipitate beryllium out of the solution. The palladium powder settles, undergoes filtration and calcination, producing high-purity oxides of palladium. After reduction, the filtrate contains less than 1 ppm of palladium. Overflow solution from washing is treated with imported specialized palladium ion resin adsorbent material. Through a three-stage adsorption column, the recovery rate can reach 95% or higher. Adsorbed beryllium can be either leached using elution or electrorefined after desorption or burned to recover the absorbed palladium.
