Mesoporous silica electrochemical sensors for the detection of ascorbic acid and uric acid; [Sensor elektrokimia silika berliang meso untuk pengesanan asid askorbik dan asid urik]

Mesoporous silica of SBA-15 and SBA-16 were successfully synthesized via the surfactant templating technique using tetraorthosilicate (TEOS) as the silica source and both surfactants, pluronic P123 and F127. Two different modified carbon paste electrodes (MCPE) were fabricated; SBA-15/MCPE and SBA-1...

Mesoporous silica of SBA-15 and SBA-16 were successfully synthesized via the surfactant templating technique using tetraorthosilicate (TEOS) as the silica source and both surfactants, pluronic P123 and F127. Two different modified carbon paste electrodes (MCPE) were fabricated; SBA-15/MCPE and SBA-16/MCPE in compared to unmodified electrode, carbon paste electrode (CPE), for ascorbic acid (AA) and uric acid (UA) determination. Due to the unique properties of mesoporous silica materials, the MCPE fabricated exhibits greater surface enhancement effect, offers better adsorption and increases the response signals of AA and UA towards both MCPEs compared to CPE. The electrochemical behaviours of AA and UA were investigated using cyclic voltammetry. Finally, the electrochemical methods were successfully applied in detection of AA and UA. © 2016, Malaysian Society of Analytical Sciences. All rights reserved.
