L-Cysteine methyl ester modified graphite powder (Cyscarbon) was used as a material to remove palladium ions from aqueous media. Cheap graphite powders (2-20 mu m in diameter) were surface functionalised with L-cysteine methyl ester. The removal of Pd(II) ions was studied as a function of concentration of Pd(II) ions, contact time with modified carbon and amount of modified carbon used. Determination of palladium ions was performed by adsorptive stripping voltammetry using a mercury nanodroplet array modified glassy carbon electrode. Dimethylglyoxime (DMG) was used as chelating agent for palladium. It was found that 1 g of Cyscarbon takes up 60 mu M palladium ions from 25 mL of 100 mu M palladium ion samples whilst the recovery experiment carried out by stirring the palladium Cyscarbon with DMG gave a yield of 45% (optimised).
