Synthesis of a-Zirconium Phosphate and its Application in Glucose Electrochemical Sensors
A facile protocol was described for immobilizing glucose oxidase in the interlayer regions of layered α-zirconium phosphate (α-ZrP) under ambient conditions at pH7.0. Then, the GOx / α-ZrPs composites as prepared were immobilized on the glassy carbon electrode surface using ehitosan. The biosensor could be used for the detection of glucose, and the linear range was 0.01-20 mmol/L with a related coefficient of 0.996. The sensitivity wag 4.74 μA / (mmol/L) and the detection limit Was 0.01 mmol/L.
