Derivation of Pseudo-First-Order, Pseudo-Second-Order and Modified Pseudo-First-Order rate equations from Langmuir and Freundlich isotherms for adsorption

Chemical Engineering Journal, 2020
Abstract The kinetics of adsorption for Langmuir and Freundlich isotherms has been explored theoretically on the basis of Statistical Rate Theory (SRT). The Modified Pseudo-First-Order (MPFO) and Pseudo-First-Order (PFO) models were derived from Freundlich isotherm on the basis of Statistical Rate Theory at c 0 ≫ c e and at close to ...

Pseudo first-order kinetics

Journal of Chemical Education, 1972
A kinetic study of second-order reactions under first-order conditions can yield accurate second-order rate constants provided an empirical allowance is made for the depletion of the reactant in ex...

What’s wrong with Lagergreen pseudo first order model for adsorption kinetics?

Chemical Engineering Journal, 2016
Abstract Adsorption processes can be modeled on the basis of phenomenological principles using conservation, equilibrium and transport kinetics equations. However many times an empirical approach is followed using pseudo first order and pseudo second order models to describe adsorption kinetics.

Thermoluminescence with pseudo first-order kinetics

Journal of Physics D: Applied Physics, 1982
In the context of thermoluminescence emission, first-order kinetics is defined formally as the case where every electron, having escaped from a trap, recombines with a trapped hole without first being re-trapped. Rather surprisingly, most studies of the kinetic order of thermoluminescence report first order. Two previously recognised conditions leading

Pseudo First-Order Adsorption Kinetics of N719 Dye on TiO₂ Surface

ACS Applied Materials & Interfaces, 2011
We have investigated the adsorption kinetics of Ru-based N719 dye on TiO(2) surface in dye-sensitized solar cell using 0.5 mM and 5 mM dye solutions. The amount of adsorbed dye on TiO(2) surface of ca. 5 μm-thick film was measured as a function of immersion (adsorption) time.

Enhanced Kinetics of Pseudo First-Order Hydrolysis in Liquid Phase Coexistent with Ice

The Journal of Physical Chemistry A, 2013
The reaction rate of the hydrolysis of fluorescein diacetate (FDA) is several times larger in the frozen state than that in the unfrozen solution of the same composition at the same temperature. The freeze concentration of reactants in the liquid phase expelled form ice crystals cannot explain the kinetic enhancement of pseudo first order reactions ...
