Sustainable and Environmentally Friendly Approaches for Eliminating Alizarin Red S from Contaminated Water Using Hydroxyfluorapatite-Based Biomaterials
Abstract
This study investigated the use of new bioadsorbent the Hydroxyfluorapatite (Ca10(PO4)6OH1.75F0.25, HFA) to eliminate Alizarin Red S (ARS), a harmful water pollutant. Initial batch tests were conducted to evaluate the adsorption process, focusing on both kinetics and equilibrium behavior. Various kinetic models were applied such as: pseudo first-order, pseudo second order, the intra [...]
