Innovative Synthesis and Characterization of Nano Hydroxyapatite: A Potential Adsorbent for Methyl Violet 6B Removal from Aqueous Solutions

Abstract: In this study, the use of nano Hydroxyapatite (HAp) adsorbent as an adsorbent for the removal of methyl violet 6B (MV 6B) dye from aqueous solution was investigated. Nano adsorbent characterization was carried out by X‐Ray Diffractometer (XRD), scanning electron microscopy (SEM), spot energy dispersive spectroscopy (EDS) analyses. The dye removal study was carried out using the classical batch adsorption process. In addition, isotherm, kinetic and thermodynamic adsorption studies were carried out for methyl violet 6B. In adsorption studies, the effects of initial dye concentration (10–40 mg/L), solution pH (2‐8), adsorbent dosage (0.5–2.5 mg) and contact time (15–90 min.) on dye removal were investigated. At dye concentration was 10 mg/L, adsorbent dosage was 1 mg, solution pH was 6, contact time was 30 min and ambient temperature 25 °C, the highest MV 6B removal was 95.86 % and 1200 mg/g adsorption capacity was obtained. As a result of adsorption isotherm and kinetic studies, it was observed that the adsorption values obtained from the models were compatible with Langmuir isotherm model and pseudo‐second order kinetic model. According to the thermodynamic data obtained, it was determined that the adsorption process was spontaneous and exothermic.
