Abstract
The content and modes of occurrence of phosphorous (P) in eight biomass ashes (BAs) were studied. It was found that BAs are enriched in P as its concentration varies in the range 0.3–4.4% (mean 1.7%). The highest contents of P (>2 %) are characteristic of ashes produced from agricultural residues, namely plum pits, sunflower shells and corn cobs. It was identified that the modes of P occurrence in BAs are related mostly to apatite and whitlockite. Hence, BAs having renewable and C-neutral origin could be alternative and very perspective resource for the potential recovery of P and its utilization in industry in contrast to finite and non-renewable phosphate rocks.
