请教一下，该文献中用的应该是铂丝电极还是铂片电极？ The platinum electrodes were washed ultrasonically with hexane, acetone, isopropanol and distilled water. Then, they were heated at 60◦C for 30 s with a solution comprising a 1:1:5 volume ratio of aqueous ammonia (0.1 M), hydrogen peroxide (20%) and distilled water. The electrode surfaces were then polished with 0.05-m alumina slurry paste and any residual abrasive particles were removed ultrasonically in water. After polishing, the glassy carbon electrode was rinsed with potassium hydroxide solution and finally soni-cated in an ethanol and water mixture. An exactly weighed amount of microgel particles, 3 mg, was placed and held at the electrode surface by a dialysis membrane. The resulting electrode was washed with phosphate buffer and +0.6 V ver-sus SCE (GOx-platinum electrode) and −0.1 V versus SCE (PPO-glassy carbon electrode) constant potential was applied until the background current decreased to a constant level. |
