) Abstract: By using sodium sulfite as reductant and Cl- and composited halogen ions as catalysts, selenium and tellurium were recovered and gold, platinum and palladium were captured from precipitated.... The results show that the reduction rates of selenium, gold, platinum and palladium are 100.0% and the reduction rate of tellurium is 97.7% when Cl- concentration is 1.1 mol/L,reaction temperature is 85......
by conducting a mass flow rate analysis using the STAN program.The results show that considerable amounts of gold, silver, cobalt, palladium,and copper could be recovered.This will reduce the amounts......

). Firstly, the preceding palladium particles as catalysts induce the nucleation of nickel. Secondly, the nickel particles induce the deposition of molybdenum and phosphorus, which attributes to induced..., although the semi-bright monolayer disappeared, palladium could be detected on the surface and it still showed no trace of the elements of nickel, molybdenum and phosphorus. Figure 1(c) illustrates......
