As a raw material, phosphorus availability in agriculture has been a critical concern in terms of phosphate rock consumption related to a price-dependent supply-demand chain. Novel approaches have been proposed for alternative phosphorus sources in agricultural applications. Although nano-hydroxyapatite (nHA) is a commonly used bioceramic material, its utilization as an alternative phosphorus fertilizer is an emerging field. Phosphogypsum (PG), a by-product of wet process phosphoric acid production, is a promising raw material for nHA production. With an approximate 300 Mton annual accumulation rate of PG puts pressure on the research for introducing alternative strategies for the resource utilization of legacy PG piles in an environment-friendly and cost-efficient manner. Valorization of PG as the calcium and phosphorus precursor in nHA production would both provide an efficient waste management strategy and low-cost raw material. This study gives a brief review of the various synthesis routes on PG-derived nHA and criticizes nHA utilization as a phosphorus fertilizer.

“…The minerals in those layers could have potential application in the remediation of environmental contamination of uranium or in the construction of barriers in deep geological repositories of uranium wastes of nuclear industry [4][5][6][7][8][9][10]. Historically, it has been reported that one absorbent of uranium is hydroxyapatite, although its absorption mechanism is still under discussion [11][12]. Up to now, the studies of such barriers have been focused on the sorption of uranium in zirconium oxides, bentonites, calcareous clays and synthetic phosphates [13][14][15][16][17][18].…”

Composition and properties of tectosilicate-uranium layers of soil

et al. 2012

Structure and superficial properties of tectosilicates found in soils with potential to retain uranium are studied in this work. These tectosilicates are largely available as natural minerals in the soil and are composed mainly by anorthite (CaAl2Si2O8), albite (NaAlSi3O8) and orthoclase (KAlSi3O8), in which albite has approximately 3 times the content of orthoclase and 2.5 times the content of anorthite. However, anorthite has a double cell structure, which could result in approximately the same sorption effect as albite. The acidity constants calculated with the surface complexation model suggested that the three components have similar amphoteric behavior in presence of high ionic strength ground salt solutions. The composite mineral has a specific surface area of 20.5 m 2 g-1 with site density of 2.8 sites nm-2. These characteristics make this mineral a good candidate for uranium capture.
