WebNov 11, 2024 · The graph of pseudo first order and pseudo second order were plotted log (qe-qt) and t/qt versus t then the value of qe, K1and K2 were calculated from the intercept and slope that were obtained ... WebApr 10, 2024 · The adsorption kinetics (pseudo-first order and pseudo-second order), isotherms (Langmuir, Freundlich, and Temkin), and thermodynamics (ΔG°, ΔS°, and ΔH°) were also studied. The Langmuir adsorption isotherm showed a linear correlation coefficient (R2) equal to about 1 for all the dyes, indicating that the adsorption occurred as a ...

WebMar 16, 2024 · As per the study, hydrolytic degradation of oxytocin at lower pH (~ 2) follows pseudo-first-order degradation kinetics (Hawe et al. 2009). Parameters for degradation kinetics. Rate constant, activation energy, half-life, shelf life, and mean kinetic temperature are the primary parameters measured in degradation kinetics. Rate constant can be ... WebFeb 24, 2024 · The fitting of the pseudo-first-order seems to be poor, and the pseudo-second-order is comprehensively better. However, the whole adsorption process is well fitted to the intragranular diffusion, which means that the reaction is in the form of a physical and chemical reaction, combined with intragranular diffusion [ 44 ]. horror chat game

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 ln(2)≈0.693). A typical first-order reaction has a lifetime τ = 1/k.. Fractional order. In fractional order reactions, the order is a non-integer, which often indicates a chemical … WebThis equation describes the pseudo-first order association kinetics of the interaction between a ligand and its receptor, or a substrate and an enzyme.
