The characteristics of diffusion currents of anodic reaction of iodide ions in concentrated iodine-iodide solutions have been studied, using a rotating disk electrode. It is found that the anodic diffusion currents are not controlled by the diffusion of iodide ions toward the electrode, but by that of the product iodine from the electrode to the solution. The diffusion limiting current densities are directly proportional to the △m_(I2,max), which is defined as unsaturated extent of iodine, and it is different...

The characteristics of diffusion currents of anodic reaction of iodide ions in concentrated iodine-iodide solutions have been studied, using a rotating disk electrode. It is found that the anodic diffusion currents are not controlled by the diffusion of iodide ions toward the electrode, but by that of the product iodine from the electrode to the solution. The diffusion limiting current densities are directly proportional to the △m_(I2,max), which is defined as unsaturated extent of iodine, and it is different in the definition and the value from the usual degree of unsaturation of iodine in the electrolyte solution.

本文对碘化钠-碘浓溶液体系中碘离子阳极氧化扩散电流的性质进行了研究.指出在这种体系中,阳极扩散电流不由碘离子向阳极的扩散速度所控制,而是由阳极电解产物碘由电极表面向溶液中的扩散所控制;其极限扩散电流密度与本文中定义的碘的未饱和度△m_(I_2),max成正比,后者是一个与通常所指的碘的不饱和度在意义和数值上都不相同的物理量.

The thermodynamic aspects of gold dissolution in different electrolytes were discussed.The Eh-pH diagram for the gold-iodide-water was studied and the gold-iodide system showed the largest stability region in aqueous environments.The mechanism leaching gold with iodide-iodine was analyzed.The dissolution of gold bearing ore was studied using iodide-iodine solution as lixiviant.The influence of reaction time,iodide-iodine concentrations and pH on gold extraction and gold leaching using iodide-iodine and cyanide was compared.The direct electrowinning of gold from dilute iodine-iodide solutions employing a three-dimensional cathode cell and recyclable iodine were studied.The rational qualifications of leaching gold were elicited:iodine concentration 0.8%~1.0%,n(I2)∶ n(I-)=1 ∶ 8~1 ∶ 10,H2O2 concentration 1%~2%,the leaching time 4 h,the ratio of liquid on solid 3∶1~5∶1,leaching gold at normal temperature,the area of pH 0~14.Gold leaching recovery is more than 93%,Gold and iodide in the electrolyte can be reclaim with electrowinning.
