Abstract
Apatitic tricalcium phosphate powder (ATrPh-105) was synthesized and characterized using different characterization techniques (XRD, FTIR, N2-physisorption, Laser diffraction, SEM, TEM, and ICP analysis). The potentiality of ATrPh-105 was investigated to remove Cr(VI) from the environmentally relevant water. We performed sorption tests on solutions containing chromium ion (Cr(VI)) and studying different parameters (pH, temperature, and concentration). ATrPh-105 could effectively adsorb Cr(VI) through chemical sorption. The sorption of Cr(VI) on ATrPh-105 is strongly dependent on pH and sorption kinetics followed a pseudo-second-order model. The Langmuir isotherm describes well isotherm data with a maximum sorption capacity up to 527.19 mg/g at 60 °C and pH 3.0. These acquired outcomes suggested that ATrPh-105 had a great potential as an economic and efficient adsorbent of Cr(VI) from contaminated water, which has huge application potential.
