چکیده

A modification glassy carbon electrode was fabricated as biosensors by mechanical attachment with carbon nanotubes to detect the effect of different concentrations of ascorbic acid (AA) on mercury ions in blood of human healthy samples using cyclic voltammetric technique. The oxidation potential peak of mercury ions in blood medium was appeared at 0.2 V, while the same peak in KCl as a supporting electrolyte appeared at 0.25–0.3 V. It was observed that the different concentrations of AA which are added to the mercury ions enhanced the oxidation current peak by raising the formation of decomposition complex in blood composition. This phenomenon appears while using seafood with lemon juice (as AA) which leads to the death if the percentage of mercury ions in the seafood was high. AA with mercury ions in blood media works as electrocatalysis by enhancing the oxidation current peak of mercury ions. It was very important to use the biosensor in the higher indicating analysis of the decomposition of the damage blood with higher sensitivity.
