Abstract
This paper presents the synthesis of nano hydroxyapatite using deposition process and eggshell as a cost-effective starting material. This study investigates its potential as an effective adsorbent for heavy metals. Various analytical techniques, including X-ray diffraction (XRD), X-ray fluorescence spectroscopy (XRF), Fourier transform infrared (FTIR), surface area measurement (BET), and scanning electron microscopy (SEM), were used to characterize the composition. The main objective was to evaluate the suitability of the synthesized hydroxyapatite as a heavy metal adsorbent in aqueous solutions. The results of this research showed that hydroxyapatite, which has a particle size in the range of nanometers and a specific area of 150 square meters per gram, and has the necessary properties for absorption, was successfully processed. The results showed that the prepared samples had a uniform mesopore distribution between 2 and 3 nm and 6 and 20 nm.
