Mutual effects of cadmium and phosphate on their adsorption and desorption by goethite

Wang, Kaijun, Xing, Baoshan·2004·Environmental Pollution

Abstract

Adsorption of cadmium (Cd) and phosphate by oxides or soils has been extensively studied, but the adsorption/desorption kinetics and mutual effects of these two species in co-existing systems has received little attention. In this study, a batch equilibration method was used to investigate the effect of phosphate and its application time on Cd adsorption and desorption on goethite. The influence of Cd and its application time on phosphate sorption and desorption kinetics was also determined. For Cd adsorption, phosphate was introduced into the system by two sequences: pre-treating goethite at 40 (degrees)C for 1 week, and applying with Cd simultaneously. Similarly, for phosphate sorption, Cd was applied by pre-treating goethite at 40 (degrees)C for 1 week or simultaneous addition with phosphate. Results demonstrated that phosphate added to goethite enhanced Cd adsorption, and facilitated Cd release as compared to untreated goethite. Cadmium had slightly higher adsorption, but a significantly faster desorption rate from the goethite simultaneously treated with phosphate and Cd, as compared to phosphate-pretreated goethite. Cadmium and its application time had little impact on phosphate sorption by goethite. However, phosphate desorption kinetics was affected by Cd application time. When the sorption time was short (15 min), phosphate desorption was faster from the goethite that was simultaneously treated with phosphate and Cd, as compared to Cd pretreated or untreated goethite. In contrast, a longer sorption time (4 weeks) resulted in a higher desorption rate of phosphate from Cd pretreated goethite than simultaneously phosphate-Cd treated goethite. This study provided useful information on adsorption/desorption kinetics in complicated Cd-phosphate-goethite systems.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
