Dataset on calcium ferrites for dye and phosphate removal

The dataset provides an experiment-level record of the synthesis conditions, physicochemical characterisation, and functional performance of calcium ferrite materials. The dataset integrates information across multiple experimental domains, including: Synthesis descriptorsCa:Fe ratio, precursor chemistry, calcination temperature, synthesis route and processing parameters. Phase and material descriptorsPredominant and secondary crystalline phases, qualitative phase composition, and phase evolution across synthesis conditions. Physicochemical propertiesSpecific surface area, particle size distribution, zeta potential, magnetic parameters, and complementary material properties. Functional performance outcomesRemoval capacity and efficiency for dyes and phosphate under defined experimental conditions, including exposure time, concentration, and pH. The dataset is organised at the level of individual experiments and is intended to support: reproducibility and cross-study comparison, data-driven analysis of structure–property–function relationships, Safe-and-Sustainable-by-Design (SSbD) assessment and optimisation. Where applicable, the dataset includes references to the corresponding experiments reported in the associated research manuscript.
