Electroanalytical methods in detection and characterization of elemental sulphur nanoparticles in the seawater environment

Electroanalytical methods, voltammetry and chronoamperometry were applied for detection and characterization of reduced sulphur species in euxinic seawater. Colloidal finest fraction, i.e. elemental sulphur nanoparticles (S(0) NPs), were detected. Chronoamperometric signals recorded in acidified euxinic seawater samples were used for evaluation of S(0) concentration and size of formed NPs. The observed results indicate a great potential of chronoamperometic measurements in characterization of similarly sulphur containing NPs (metal sulphides) in aquatic environment.
