Pseudo-first-order kinetics翻译
WebThe degradation kinetics of imidacloprid followed pseudo first-order kinetics and reaction rates related to PMS and Co2+, concentrations. The reaction rates increased with increasing [PMS] and [Co2+] when the other parameters were constant. However, the decrease of degradation rates was found when the molar ratio of PMS versus imidacloprid was ... WebHere stands for concentration in molarity (mol · L −1), for time, and for the reaction rate constant. The half-life of a first-order reaction is often expressed as t 1/2 = 0.693/k (as …
