Ozone monitoring based on a biosensor concept utilizing a reagentless alcohol oxidase electrode.

摘要: An electrochemical method based on the concept of a biosensor for monitoring ozone is described first time. The proposed includes two parts:  selective sorbent ozone, that is, eugenol, and formaldehyde amperometric mounted into flow-through cell. Ozone adds rapidly to double bond allyl group which has been immobilized onto hydrophobic C-18 reactor so produced collected working buffer solution (sampler) pumped detector. A multimembrane assembly consisting an alcohol oxidase-modified nylon membrane sandwiched between outer polycarbonate inner cellulose acetate was fitted Pt electrode enzymatically H2O2 monitored at +0.65 V (vs Ag/AgCl/KCl 3 M). Under optimum conditions, linear calibration curve over concentration range 3−200 μg·mL-1 constructed. detection limit (S/N = 3) calculated 1.1 ozone. int...
