Sažetak
Chronopotentiometric features of peak recorded in the buffer solutions of selected marine polysaccharides (PS) at different conditions (accumulation potential, accumulation time, stripping current, buffer concentrations) will be presented. According to the electrochemical properties and rules serving as a tool to differentiate between faradaic and catalytic process, it will be proven that obtained peak possesses catalytic characteristics on mercury electrode, so it is called “peak HPS”. Sulpho- and carboxyl groups could be identified as catalytic groups in the PS structure. Dependence of “peak HPS" on accumulation potential could give the information about PS conformation. Reproducibility could be assured in the buffered electrolyte only.
