摘要/Abstract

Abstract: In presence of a cationic surfactant HTAB,linear potential scans for Na 2S at graphite anode in both saturated sodium tetra_borate solution and 1 mol·L -1 NaOH solution, have been investigated.Results show that anodic current density increases and peak potentials shift to more negative with the increase of HTAB concentrations. The anodic current densities increased by addition of HTAB are larger in 1 mol·L -1 NaOH than those in saturated sodium tetra_borate solution,resulting from different acting forces of HTAB with various charged electro-active species .Both oxidation and reduction peaks in cyclic voltammograms for Na 2S containing solution become sharper if HTAB is present in the anolyte. The appearance of several reduction peaks indicates that intermediate polysulfides are produced in negative-going scan.

Key words: Sodium sulfide, Cyclic voltammetry, Surfactant, Electrolysis
