摘要: Abstract The inhibition of the electrode reaction Cd(II) in seawater as supporting electrolyte presence non-ionic surfactant T-X-100 was studied by differential pulse polarography a wide concentration range (10 −7 −5×10 −4 mol dm −3 ). kinetic parameters, rate constant k s and transfer coefficient α were estimated from shape height corresponding polarograms, using theoretical curves obtained digital simulation.
