Apatite Control of Phosphorus Release to Runoff from

2009-1-11 · Phosphorus (P) in runoff can pose a water quality risk in phosphate mine reclamation areas. High dissolved P (DP) concentrations (about 0.4–3.0 mg L −1) in runoff from these areas and high equilibrium P concentrations for the soils led us to hypothesize that P release is controlled by dissolution of apatite rather than by desorption mechanisms.

Apatite Control of Phosphorus Release to Runoff from

2009-11-30 · Phosphorus in soils constructed from sand tailings atthe remediation sites was in the form of apatite, asindicated by XRD and corroborated by XRF elemen-tal analysis and chemical fractionation. Results of thisstudy supported the hypothesis that release of P fromthe soils was primarily from apatite dissolution ratherthan desorption from metal oxides that is more typicalof soils of the region. The DP concentration in a batchexperiment is closely related to the calculated CFASSA. Results show that these soils are a P sourcerather than sink. Findings are applicable to otherphosphate mine
