The Application of Hydroxyapatite NPs for Adsorption Antibiotic from Aqueous Solutions: Kinetic, Thermodynamic, and Isotherm Studies

Antibiotic pollution has become a serious concern due to the extensive use of antibiotics, their resistance removal, and detrimental effects on aquatic habitats humans. Hence, developing an efficient antibiotic removal process for aqueous solutions vital. Amoxicillin (Amox) is one antibiotics that been efficiently removed from solution using hydroxyapatite nanoparticles (HAP NPs). The current study synthesizes utilizes as cost-effective adsorbent. Adsorbent dose, pH solution, initial Amox concentration, equilibrium time, temperature are among factors have evident impact adsorption. (200) mg (5), (25) °C, time (120) min shown be best-optimized values. nonlinear Langmuir’s isotherm pseudo-second-order kinetic models with capacities 4.01 mg/g highly compatible experimental adsorption data. parameters thermodynamic analysis show onto HAP NPs powder spontaneous exothermic.
