Experimental study of the effect of pH on the kinetics of montmorillonite dissolution at 25 °C
Abstract The effect of pH on the kinetics of smectite (K-montmorillonite) dissolution was investigated at 25 °C in batch and stirred flow-through reactors over the pH range of 1–13.5, in KNO3Expand

Critical conditions for ferric chloride‐induced flocculation of freshwater algae
The effects of algae concentration, ferric chloride dose, and pH on the flocculation efficiency of the freshwater algae Chlorella zofingiensis can be understood by considering the nature of theExpand

Kinetics of quartz dissolution at low temperatures
Quartz dissolution rates have been measured as a function of pH and ionic strength at 25° and 60°C and can be modeled by a rate law which takes into account speciation at the quartz-solutionExpand

Biodegradation of Uranium−Citrate Complexes: Implications for Extraction of Uranium from Soils
Citrate is often used as a complexing agent to mobilize sorbed and precipitated uranium in both in situ and ex situ extraction of soils and nuclear reactor components. The biodegradability ofExpand

Surface chemistry of K-montmorillonite: ionic strength, temperature dependence and dissolution kinetics.
The surface chemistry of K-montmorillonite was investigated by potentiometric titrations conducted at 25, 50 and 70 degrees C and at ionic strengths of 0.001, 0.01 and 0.1 M KNO(3). Proton adsorptionExpand

Surface complexation clues to dolomite growth
Calcium and magnesium adsorb in near-stoichiometric proportions to dolomite over wide ranges in [Ca{sup 2+}]/[Mg{sup 2+}], ionic strength, and solution composition pointing to minimal mixing of metalExpand

Boehmite sorbs perrhenate and pertechnetate
Boehmite and Al-oxyhydroxide gels sorb ReO4-, a non-radioactive analogue of TcO4- from NaNO3 solutions. Sorption appears to be substantially electrostatic (though there appears to be a specificExpand

Effects of Clay Minerals on Cr(Vi) Reduction by Organic Compounds
The objective of this study is to examine the effect of clayminerals (illite, montmorillonite, and kaolinite) on chromate (Cr(VI)) reduction by several low molecular weightorganic compounds. BatchExpand
