 · Flotation separation of strontium (Sr) from wastewater via phosphate precipitation was investigated. While % of Sr precipitated at highly alkaline pH in the absence of PO 4 3−, it completely precipitated as Sr 3 (PO 4) 2 at a molar ratio ([PO 4 3−]:[Sr 2+]) of at a lower pH presence of Ca 2+ hindered Sr precipitation, yet it could be overcome by increasing the PO .
