摘      要：Platinum adsorption on activated carbon,a common adsorbent,from dilute platinum-containing solution of 57.6 mg/L was *** effects of different adsorption parameters on the platinum adsorption were reported in *** percentage of platinum adsorption increased with increasing the amount of adsorbent,as well as with increasing contact time and temperature.A platinum adsorption of 75% was obtained using 400 mg of activated carbon at a shaking rate of 200 r/min for 3 h at 25 ℃.A platinum adsorption of 88%,however,was obtained at 80 ℃ using 200 mg of activated carbon within only 1 h,which indicates that temperature plays a vital role in the adsorption process.A platinum adsorption of 99% or above was attained using 400 mg of activated carbon after contact for 3 h at 80 ℃.
