Abstract: 【Objective】The objective of the study is to disclose the structural characteristics and their internal relation with phosphorus validity in the promoted-release phosphate rocks (PRPr), and discuss the method for quantitative determination of active phosphorus.【Method】Continuous water extraction (CWE) and digestion with acetic acid and sodium acetic mixture (ASA) were involved, and the re-activated experiments and spectroscopic techniques were carried out to explore the phosphorus validity mechanism of PRPr from promoted-release persistence and molecular structure.【Result】The water-soluble phosphorus and active phosphorus in PRPrs treated by sodium lignosulphonate (SL) increased significantly. Compared with the phosphate rocks, the accumulative release rates of phosphorous of four PRPrs were 14.0, 5.6, 8.8 and 5.1 times higher and active phosphorus in PRPrs increased by 9.8%-93.1%, respectively. The results of infrared spectrum (IR) and X-ray diffraction（XRD）analysis showed that the characterastic abasorption spectrum of H2PO42- was strengthened or new characterastic absorption spectrum of H2PO42- appeared, the structure of apatite crystal was destroyed and amorphous apatite increased. These constantly made insoluble and citrate-soluble phosphorus in phosphate rock changed into active status and improved the bioavailability of phosphorus.【Conclusion】The promoted-release treatment could significantly improve the bioavailability of phosphorus in phosphate rock through constantly translate insoluble and citrate-soluble phosphorus into active status. The continuous water extraction and ASA can be used to make a proper assessment on bioavailability of PRPrs.
