Mobility of Pb, Cu, and Zn in the phosphorus Phosphorus-bearing materials have been widely applied in immobilization of heavy metals in contaminated soils. However, the study on the stability of the initially P-induced immobilized metals in the contaminated soils is far limited. This work was conducted to evaluate the mobility of Pb, Cu, and Zn in two contrasting contaminated soils amended with phosphate rock tailing (PR) and triple

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. In the PbeCueZn ternary system, competitive metal sorption occurred with sorption capacity reduction of 15.2%, 48.3%, and 75.6 % for Pb, Cu, and Zn, respectively compared to the mono-metal systems. A fractional factorial design showed the interfering

(PDF) Phosphate Recycling in the Phosphorus Heavy metals (Cu, Zn, Cr, Ni, Cd, As, and Pb) and organic micropollutants in CaP granules were below the Dutch and European regulatory limits for direct fertilizer application. Moreover Phosphate-induced metal immobilization in a Phosphate amendment also modified Zn and Cu distribution in soil, with an increase in residual Zn and Cu . The main transformation for Cu was the reduction of carbonate and Fe–Mn oxide fractions, and for Zn was the reduction in exchangeable, carbonate and organic fractions. Phosphate treatment increased residual Zn by 6–16% and Cu by 3–14% across the treatment. Obviously, P amendment was

Trace- and rare-earth element geochemistry and The Lower Cambrian black shale sequence of the Niutitang Formation in the Yangtze Platform, South China, hosts an extreme metal-enriched sulfide ore bed that shows >10,000 times enrichment in Mo, Ni, Se, Re, Os, As, Hg, and Sb and >1,000 times enrichment in Ag, Au, Pt, and Pd, when compared to average upper continental crust. We report in this paper trace- and rare-earth-element concentrations

Phosphate - WikipediaPhosphates are the naturally occurring form of the element phosphorus, found in many phosphate minerals. In mineralogy and geology, phosphate refers to a rock or ore containing phosphate ions. Inorganic phosphates are mined to obtain phosphorus for use in agriculture and industry. The largest global producer and exporter of phosphates is Morocco.

A fractional factorial design showed the interfering Competitive Adsorption of Heavy Metals by The competitive adsorption of Cd, Cu, Pb, and Zn from 0.025 M NaClO 4 solutions onto four soils with differing chemical properties was investigated with batch adsorption experiments. For two mineral soils, adsorption under acidic conditions (pH 5.0) followed the sequence Pb > Cu > Zn > Cd, which corresponds to the order of increasing pK for the first hydrolysis product (e.g., PhOH +) of the Phosphate amendment of metalliferous T1 - Phosphate amendment of metalliferous tailings, Cannington Ag-Pb-Zn mine, Australia: T2 - implications for the capping of tailings storage facilities.
