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.

Spectrochemical evaluation of first order and pseudo-first order reactions following charge transfer for chronoamperometry at transparent electrodes

Journal of Electroanalytical Chemistry, 1970
Summary Relationships for spectrochemical evaluation of first-order and pseudo-first-order reactions following reversible electron transfer have been developed for chronoamperometry at optically transparent electrodes. Computer generated curves for the time dependent absorbance are presented for the general case where both electro-chemical and ...

Simulation of 1,3-dichloropropene in topsoil with pseudo first-order kinetics

Journal of Contaminant Hydrology, 1995
Abstract For fast-degraded chemicals such as 1,3-dichloropropane (1,3-D), their long persistent time in topsoils cannot be explained by the ordinary first-order kinetics of biodegradation that is commonly used in the simulation of chemical transport in soils.

Exact Asymptotic Relaxation of Pseudo-First-Order Reversible Reactions

Physical Review Letters, 1997
The relaxation kinetics of the diffusion-influenced reversible reaction $A+B\ensuremath{\rightleftharpoons}C$ is studied in the pseudo-first-order limit $([B]\ensuremath{\gg}[A])$ when A and C are static and the B's move independently with diffusion coefficient D. For the initial condition $[A(0)]\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1$, $[

Pseudo-first-order phase transitions in one dimension

Journal of Physics A: Mathematical and General, 1979
A study is made of the one-dimensional Ginzburg-Landau system with a cubic term, a model of the first-order phase transition. Fluctuations are taken into account by means of the WKB method. It is pointed out that the transition is of continuous type for any value of the coefficient of the cubic term.

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 ...

The study of bimolecular reactions under non-pseudo-first order conditions

Biophysical Chemistry, 2005
In this work a new equation which describes the time evolution of bimolecular reactions is derived and tested by experiment. The equation is general and the results show that second-order reactions of any simple type may be accurately described by a quotient of exponential functions. The model and reagent concentration dependent observed rate constants
