- 中文摘要: The diffusion coefficients of sulfide ion in 5 M NaOH solution with concentrations of (0.02-0.3)M at temperatures 24-50.degree.C were determined using a rotating-ring-disc Pt electrode to be (0.5-2.0)*10/sup -5/cm/sup 2//sec. The reaction order of the sulfide oxidation to sulfur was calculated to be 0.42 which implies one-electron transfer as the rate-limiting step and the reaction rate constant was found to be k/sub f/=2.57*10/sup -5/ exp(-0.14ZF/sub .eta.//RT).
