Rock Phosphate Acidulation Study with FTIR, XRD, and SEM Analysis

An investigation details the partial conversion of rock phosphate into more soluble calcium phosphate phases using acetic acid and monocalcium phosphate solutions. The study, authored by Youness Sedki Alaoui and last updated in April 2026, analyzes the resulting mineral phases using FTIR, XRD, XRF, SEM, and EDS. Results indicate the formation of phases like calcium-deficient hydroxyapatite and dicalcium phosphate, with these more soluble minerals constituting up to 27% of the product.

Use Cases

• Training models to predict mineral phase formation based on acidulation conditions described in the study.
• Analyzing correlations between spectroscopic data (FTIR, XRD) and mineral solubility mentioned in the results.
• Benchmarking material transformation processes against the described formation of protonated phosphate and calcium-deficient hydroxyapatite.

Strengths

• Analysis includes multiple characterization techniques: FTIR, XRD, XRF, SEM, and EDS.
• Quantifies the formation of more soluble mineral phases, which constituted up to 27%.
• Dataset is openly shared under a CC-BY-4.0 license.

Limitations

• The dataset is a 138.0 KB DOCX file, indicating a very limited scope, likely a research paper or data sheet.
• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The description is detailed but the underlying raw data files are not specified.
