Techniques commonly employed to make these measurements suffer from a variety of problems, such as stability, the need for added reagents, issues with miniaturisation, response time. Electrochemistry is one method of sensing solution species but typical electrochemical sensors are based on membrane electrodes which can suffer from a sluggish time response and frequent clogging of the membrane. Therefore this project aims to explore the development and application of membrane-free, reagent-less, fast responding, direct contact diamond based electrochemical sensors for water quality sensing. Project aims:1. Develop an understanding of how the intrinsic electrode material properties impact on the electrochemical performance of the boron doped diamond electrode2. Application of in-situ pH control3. Development of finite element models (FEM) to complement the experimental data and so aid in choice of electrode design and operating parameters4. Development of a chlorine sensor based on diamond for chlorine sensing at low concentrations, and corresponding FEM5. Implementation of pH control may be important in 4. to quantify the response of the device, this will be investigated and modelled, integration of an internal pH sensor may also be useful6. Investigating how to overcome reference electrode instability7. Investigation of the effect of solution flow on the performance of the device
