Journal ArticleDOI
A Revised Pseudo-Second-Order Kinetic Model for Adsorption, Sensitive to Changes in Adsorbate and Adsorbent Concentrations.
TL;DR: In this article, a simple modification of the PSO rate equation was proposed, yielding d q t d t = k'C t ( 1 - q t q e ) 2.
Journal ArticleDOI
Portable and rapid arsenic speciation in synthetic and natural waters by an As(V)-selective chemisorbent, validated against anodic stripping voltammetry.
Jay C. Bullen,Aaron Torres-Huerta,Pascal Salaün,Jonathan S. Watson,Swachchha Majumdar,Ramon Vilar,Dominik J. Weiss +6 more
TL;DR: This work demonstrates the first application of an As(V)-selective chemisorbent material for simple and portable speciation of arsenic using handheld syringes, enabling high sample throughput with minimal set-up costs.
Journal ArticleDOI
Improved accuracy in multicomponent surface complexation models using surface-sensitive analytical techniques: Adsorption of arsenic onto a TiO2/Fe2O3 multifunctional sorbent
Jay C. Bullen,Janice P.L. Kenney,Sarah Fearn,Andreas Kafizas,Stephen J. Skinner,Dominik J. Weiss,Dominik J. Weiss +6 more
TL;DR: This study test the hypothesis that characterisation of the outermost surface using low energy ion scattering (LEIS) improves CA-SCM accuracy, and demonstrates how surface-sensitive analytical techniques will improve adsorption models for the next generation of composite sorbents.
Journal ArticleDOI
On the application of photocatalyst-sorbent composite materials for arsenic(III) remediation: Insights from kinetic adsorption modelling
TL;DR: In this paper, a predictive model using experimentally determined As(III) adsorption isotherms and kinetics to estimate arsenic treatment plant lifetimes was constructed, considering sorbent loading, treatment time, and batch treatment versus continuous-flow.
Journal ArticleDOI
Parasitic Light Absorption, Rate Laws and Heterojunctions in the Photocatalytic Oxidation of Arsenic(III) Using Composite TiO2/Fe2O3
TL;DR: In this paper , a hybrid experiment/modeling approach was developed to study light absorption, charge carrier behavior and changes in the rate law of the TiO2/Fe2O3 system, using UV-Vis spectroscopy, transient absorption spectrography (TAS), and kinetic analysis.
