Figure 1From: Chronoamperometric study of elemental sulphur (S) nanoparticles (NPs) in NaCl water solution: new methodology for S NPs sizing and detection Sampled DC voltammograms recorded at the Hg in the solution of pure supporting electrolyte (curve 1), and in the Na 2 S 4 solution before (curve 2) and after (curve 3) acidification. The voltammograms are recorded between −1000 mV and −400 mV vs. Ag/AgCl with potential steps of 5.1 mV.Back to article page
