Immobilization of Zn, Cu, and Pb in contaminated soils

[19]. Phosphate rock was effective in reduced Pb in physiologically based extraction test (PBET) but failed to prevent Pb phytotoxicity and Pb plant uptake on all soils tested [21]. The purpose of this study was to evaluate the effectiveness of phosphoric acid and/or phosphate rock in immobilizing Pb, Cu, and Zn in two contaminated soils.

Mechanisms of Lead, Copper, and Zinc Retention by

Mechanisms of lead, copper, and zinc retention by phosphate rock Xinde Cao, Lena Q. Ma, Dean R. Rhue , Chip S. Appel Capsule: Phosphateinduced formation of fluoropyromorphite is primarily responsible for Pb immobilization by phosphate rock, whereas Cu and Zn retention is mainly attributable to the surface adsorption or complexation.

Immobilization of Zn, Cu, and Pb in contaminated soils

Considerable research has been done on Pinduced Pb immobilization in Pbcontaminated soils. However, application of P to soils contaminated with multiple heavy metals is limited. The present study examined effectiveness of phosphoric acid (PA) and/or phosphate rock (PR) in immobilizing Pb, Cu, and Zn in two contaminated soils.

Mechanisms of lead, copper, and zinc retention by

Mechanisms of lead, copper, and zinc retention by phosphate rock. The solidliquid interface reaction between phosphate rock (PR) and metals (Pb, Cu, and Zn) was studied. Phosphate rock has the highest affinity for Pb, followed by Cu and Zn, with sorption capacities of 138, 114, and 83.2 mmol/kg PR, respectively. The mobile phase of

Immobilization of Pb, Cu, and Zn in a MultiMetal

The objective of this study is to immobilize Pb, Cu, and Zn in a multimetal contaminated soil using triple superphosphate fertilizer (TSP) and phosphate rock tailing (PR) materials, alone and in combination. The treatment effectiveness was evaluated with a column leaching experiment under simulated rainfall conditions. More than 90% of Pb and Cu were stabilized in the upper layer soil (0
