Abstract.

A new solid-state pH sensor has been constructed based on a poly 3,4-dihydro-2-hydoxyquinoxaline (HOQ) thin film electrochemically deposited onto a Pt disc electrode whose surface had previously been modified with Pt nanoparticles by electrochemical depositing from HPtCl6–H2SO4 solution at −0.2 V. The poly HOQ film was deposited from HAc–NaAc solution by cycling the potential between 0.4 V and 1.1 V. The typical response of the pH sensor and its reversibility was investigated. The emf signal was linear over the pH range of 2 to 13 with a super-Nernstian slope of 63.3 mV/pH unit. The response time ranged from several seconds at a pH of around 7 up to 2.5 min at pH 13. The performance of the pH sensor was examined by measuring organic acid, amine and amino groups on the surface of composite nanomaterial samples and sat isfactory results were obtained.
