A STUDY ON THE ADSORPTIVE VOLTAMMETRIC BEHAVIOUR OF SALICYL-FLUORONE

摘要

In the 0.3mol/L NH₄Cl supporting electrolyte,salicyl-fluorone exhibitsa sensitive adsorptive wave by using linear scanning voltammetry with Ep₁=-0.70Vand a diffusion wave with Ep₂=-0.68V（v8,SCE）at pH 2.5.On the surface of HMDE,the adsorption of salieyl-fluorone obeys Frumkin adsorption isotherm.Theadsorption coefficient（B）,and attractive factor（v）and the amount ofsaturated adsorption（Γs）have been determined.
