One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Recommanded Product: Ferrocenemethanol, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 1273-86-5, Name is Ferrocenemethanol, molecular formula is C11H3FeO
Potentiometric sulfite biosensor based on entrapment of sulfite oxidase in a polypyrrole film on a platinum electrode modified with platinum nanoparticles
The surface?of a platinum electrode has been modified with platinum nanoparticles (PtNPs) and the enzyme sulfite oxidase (SOx), was entrapped on its surface in an ultrathin polypyrrole (PPy) film. The PtNPs, with a diameter of 30?40?nm, were deposited on the Pt electrode by cycling the electrode potential 20 times from -200 to 200?mV at a sweep rate of 50?mV.s-1. Morphological evidence of the successful incorporation of SOx and the presence of PtNPs were obtained by scanning electron microscopy. Also, the electrochemical behavior of the PtNPs/PPy-SOx film was examined by cyclic voltammetry, chronopotentiometry, electrochemical impedance spectroscopy and potentiometry. Under optimized conditions, the biosensor achieved a sensitivity of 57.5?mV.decade-1, a linear response that extends from 0.75 to 65?muM of sulfite, a detection limit of 12.4?nM, and a response time of 3?5?s. The biosensor was successfully applied to the determination of sulfite in wine and beer samples. [Figure not available: see fulltext.]

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: Ferrocenemethanol, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1273-86-5, in my other articles.
