The polarographic diffusion coefficient of cadmium ion in 0.1 M potassium chloride [PDF]
Journal of Electroanalytical Chemistry (1959), 1964 The diffusion coefficient of cadmium ion in 0.1 M potassium chloride at 25[deg] was determined by an absolute method. Straight calculations using the equation derived by Jost yielded values which were too high when compared to the infinite dilution value

Evaluation Technique of Chloride Penetration Using Apparent Diffusion Coefficient and Neural Network Algorithm [PDF]
Advances in Materials Science and Engineering, 2014 Diffusion coefficient from chloride migration test is currently used; however this cannot provide a conventional solution like total chloride contents since it depicts only ion migration velocity in electrical field. This paper proposes a simple analysis
