Irreversible uptake of palladium from aqueous systems using L-cysteine methyl ester physisorbed on carbon black

Abstract:

The uptake of palladium from aqueous systems by l-cysteine methyl ester-modified carbon black (CysOMe-CB) has been investigated. A solution containing 20 ppm PdCl2 could be reduced to below the limit of detection within 15 min by using 2 mg carbon black per mL water. The Pd(ii) was spontaneously reduced to Pd(0) on the carbon black (CB) surface, likely due to the known reducing nature of oxygen-containing carbonaceous materials, although the possible concurrent oxidation of cysteine to cystin...
