TL;DR: A.A. APPELO and D.C. POSTMA as discussed by the authors present important fundamental concepts and current knowledge of groundwater geochemistry and the interaction of water, minerals, gases.

TL;DR: In this paper, As(III) adsorption on kaolinite, illite, montmorillonite, and amorphous aluminum hydroxide (am-Al(OH)3) was studied as a function of pH and ionic strength.

TL;DR: The adsorption of arsenate (As(V)) on kaolinite, montmorillonite and illite was investigated at varying pH and competing anion concentration while holding As(V) concentration (6.7 X lo-' M), clay suspension density (2.5 g L-') and ionic strength (0.1 M NaCl) constant as mentioned in this paper.

TL;DR: Arsenic sorption on a calcareous, montmorillonitic soil was investigated as a function of solution pH (2-11) at two initial As concentrations (2.0 and 20 mmol m ') as discussed by the authors.

TL;DR: In this paper, the authors present five common surface complexation models of the mineral-solution interface and their use in describing soil chemical systems, including surface species, chemical reactions, equilibrium constant expressions, and surface activity coefficients.
