Abstract:

The diffusion coefficient across the boundary between Hg203 and inactive Hg as a function of temperature increased from 1.55 plus or minus 0.01 at 23C to 1.96 plus or minus 1 at 60.1C. For iodine, using I131 tracer, in aqueous KI, and CC14, the diffusion coefficient was 0.875 plus or minus. 0.005. For iodine between 0.08 MKI in 0.001 M H2SO4 and heptane 34.6 plus or minus 0.3 was found for the diffusion coefficient. Iodine flows across the interface without any slow transfer process being involved whether from the organic to the aqueous phase or from the aqueous to the organic phase. The studies were performed using a 1 mm bore by 30 to 40 cm long vertically mounted borosilicate tube, and thermostated. Movement of the radioactive species was determined by scanning the length of the tube by scintillation counting. Author
