Removal of phosphate from wastewater is necessary for the safety public health and environmental protection.The present study used an easily available affordable biosorbent obtained pomegranate peel excision water.The biosorption behavior raw powder (RPGPP) was found negligible.The RPGPP further saponified with Ca(OH) 2 followed by Fe(III) loading to obtain Fe(III)-loaded peels (Fe(III)-PGPP), which then employed uptake.Fourier transform infrared spectroscopy (FTIR), energy dispersive X-ray (EDX) spectroscopy, scanning electron microscopy (SEM), diffraction (XRD) were characterize biosorbent.The batch adsorption test evaluate viability biosorbents removing aqueous solution.Fe(III)-PGPP determined have a pH PZC 5.40.The experimental data best explained Langmuir isotherm pseudo-second-order kinetic model.Fe(III)-PGPP had largest capacity 99.30 mg g -1 at optimum 3.0 2.5 hours contact time.From results obtained, Fe(III)-PGPP adsorbent can be regarded as effective cost-efficient material treatment phosphate-anion-contaminated water.
