Adsorption Concentration of Platinum Metals by Clinoptilolite
Ruthenium(IV) and palladium(II) adsorption from aqueous solutions on to Transcarpathian clinoptilolite has been studied under dynamic conditions. The optimum conditions for ruthenium(IV) adsorption from aqueous solutions have been established as follows: pH = 3.5–4.5 or 9.0–11.0; radius of adsorbent...

| description | Ruthenium(IV) and palladium(II) adsorption from aqueous solutions on to Transcarpathian clinoptilolite has been studied under dynamic conditions. The optimum conditions for ruthenium(IV) adsorption from aqueous solutions have been established as follows: pH = 3.5–4.5 or 9.0–11.0; radius of adsorbent particles, 0.200–0.355 mm; and velocity of solution passing through the adsorbent, 3 mm/min. For palladium adsorption from aqueous nitric acid (pH = 4.0) and ammonia (pH = 11.5) solutions, the optimum radius of the adsorbent particles was in the 0.355–0.500 mm range. Desorption of Ru IV and Pd II was performed using 6 M hydrochloric acid. The degree of ruthenium(IV) extraction under optimum conditions was 95% and for palladium(II) extraction from nitric acid and ammonia solutions the corresponding values were 81.5% and 96.8%, respectively. |
