Surface complexation modeling of zinc sorption onto ferrihydrite.
A previous study involving lead(II) [Pb(II)] sorption onto ferrihydrite over a wide range of conditions highlighted the advantages of combining molecular- and macroscopic-scale investigations with surface complexation modeling to predict Pb(II) speciation and partitioning in aqueous systems. In this work, an extensive collection of new macroscopic and spectroscopic data was used to assess the a...
متن کاملSurface complexation modeling of proton and Cd adsorption onto an algal cell wall.
This study quantifies Cd adsorption onto the cell wall of the algal species Pseudokirchneriella subcapitata by applying a surface complexation approach to model the observed adsorption behavior. We use potentiometric titrations to determine deprotonation constants and site concentrations for the functional groups on the algal cell wall. Adsorption and desorption kinetics experiments illustrate ...
متن کاملStatistical Modeling of Surface Complexation of Selenium Onto Iron and Aluminum Oxide Using SAS®
Simulation of chemical element adsorption, release, and transport is possible without the need to perform time consuming, detailed adsorption studies on multiple samples by incorporating prediction equations into chemical speciation–transport models before simulating. Adsorption models also assume that the chemical species in a mixture is at chemical equilibrium which is the state in which the ...
متن کاملLead sorpion onto ferrihydrite. 2. Surface complexation modeling.
Few studies have combined molecular- and macroscopic-scale investigations with surface complexation model (SCM) development to predict trace metal speciation and partitioning in aqueous systems over a broad range of conditions. In this work, an extensive collection of new macroscopic and spectroscopic data was used to assess the ability of the modified triple-layer model (TLM) to predict single...
متن کاملMetal sorption to ferrihydrite Phosphate effects, X-ray absorption spectroscopy and surface complexation modelling
Phosphorus affects the sorption of many metals and arsenate to iron (hydr)oxides. This may influence the mobility and bioavailability of metals and arsenate in soil and water. Phosphorus therefore plays an important role in, e.g., determining the ecotoxicological risk of contaminants in soils. The overall aim of this thesis was to improve the understanding of lead(II), copper(II), cadmium(II) a...
