Adsorption kinetic modeling using pseudo-first order and pseudo-second order rate laws: A review

open access: yesCleaner Engineering and Technology, 2020
Adsorption for water and wastewater treatment has been the subject of many research in the scientific community, focusing mainly on either equilibrium or kinetic studies. Adsorption kinetics are commonly modeled using pseudo-first and pseudo-second order

Pseudo-First-Order Transition in Interacting Self-avoiding Walks and Trails [PDF]

open access: yesComputer Physics Communications, 2001
The coil-globule transition of an isolated polymer has been well established to be a second-order phase transition described by a standard tricritical O(0) field theory.

Four-dimensional polymer collapse II: Pseudo-First-Order Transition in Interacting Self-avoiding Walks [PDF]

open access: yesPhysical Review E, 1999
In earlier work we provided the first evidence that the collapse, or coil-globule, transition of an isolated polymer in solution can be seen in a four-dimensional model.

Error Analysis of Absolute Rate Coefficient Extrapolated Under Pseudo-First Order Conditions

open access: yesJournal of the Turkish Chemical Society, Section A: Chemistry, 2017
Computer-based simulations for the three-body recombination reaction of nitrogen (II) oxide with the hydroxyl radical have been used to estimate the error associated with the pseudo-first order approximation under different simulated conditions.

Effect of pretreatment with pentanol for dyeing wool fibers at low temperature [PDF]

open access: yesActa Periodica Technologica, 2023
This paper describes the influence of pre-treatment with pentanol for the dyeing of wool fibers at low temperatures. Wool fiber is expensive to produce and process; accordingly, it must be economically viable and meet consumer demands. Acid dyes

Adsorption of Cu (II) and Ni (II) Ions from Solution onto Calcium Alginate Beads

open access: yesJournal of Applied Sciences and Environmental Management, 2020
The objective of this study was to investigate the biosorption of Cu (II) and Ni (II) ions from aqueous solution by calcium alginate beads. The effects of solution pH, contact time and initial metal ion concentration were evaluated.
