Abstract: |
The zirconium phytate/Prussian blue(Zr-IP6/PB) multilayer structure film was constructed by layer-by-layer self-assembly technology.Since Prussian blue(PB) has high electrocatalytic performance for H2O2,and the 5-layer Zr-IP6/PB membrane with porous structure is beneficial to the mass transfer process,the as-prepared hydrogen peroxide sensor shows high sensitivity and selectivity.The result showed that the linear concentration response range of such modified electrode on H2O2 is from 2.00×10-5 to 1.76×10-3 mol·L-1,and the linear correlation coefficient (R) is 0.998 9. |
