Phosphorus recovery from agricultural waste via cactus pear biomass.

ABSTRACT: In this study, the potential of cactus pear pruning waste (CPPW) as a low-cost adsorbent biomass for phosphorus (P) removal from aqueous solutions was investigated in batch mode. Biomass samples derived from cactus pear were collected and analyzed to investigate their properties when enriched with either calcium (Ca) or iron (Fe). The examination focused on the capacity of these samples to remove P. The P removal capacities were determined to be 2.27 mg g^-1, 1.33 mg g^-1, and 1.87 mg g^-1 for Ca²⁺-enriched, Fe²⁺-loaded, and Fe³⁺-loaded biomass respectively. Among the various models studied, the Langmuir isotherm model was identified as the most appropriate for accurately describing the P adsorption the enriched biomass. The ki
