| 中文摘要 | a new type of silicomolybdate-methylsilicate-graphite composite material was prepared by the sol-gel technique and used for the fabrication of an amperometric nitrite sensor. the silicomolybdic anion acts as a catalyst, the graphite powder ensures conductivity by percolation, the silicate provides a rigid porous backbone and the methyl groups endow hydrophobicity and thus limit the wetting section of the modified electrode. cyclic voltammetry, square-wave voltammetry and chronoamperometry were employed to characterize the sensor. the amperometric nitrite sensor exhibited a series of good properties: high sensitivity (1.771 mu a mmol(-1) dm(3)), a short response time (7 s), remarkable long-term stability and especially reproducibility of surface renewal in the event of electrode surface fouling. |
