Abstract Details

2011, Master of Science, Miami University, Chemistry and Biochemistry.
An automated, on-line electrochemical chlorite ion sensor is reported. A three electrode assembly modified with sol-gel solid state electrolyte enabled electrochemical measurements in electrolyte-free liquids. Flow injection analysis was coupled with the electrode assembly in an electrochemical flow cell. The optimized parameters of the flow cell were a flow rate of 0.8 mL/min and an applied potential of ~0.5V. No faradaic interference was observed from perchlorate or chlorate ions. The concentrations of two validation standards as found by the method and ion chromatography were not statistically significantly different. An on-line, electrochemical chlorine dioxide sensor is also reported that couples gas-diffusion flow injection analysis with the developed electrochemical flow cell. The optimized parameters of the flow system and detector were a flow rate of 0.75 mL/min and an applied potential of -0.05V. The detection limit was .08 mg/L and 10 mg/L solutions of chlorite, chlorate, and perchlorate ions showed no interference.
