Application of Mn-Fe Layered Double Hydroxide as an Adsorbent for the Removal of Arsenic from Synthetic Acid Mine Drainage

The Mn-Fe layered double hydroxide using chloride in the interlayer anion was successfully synthesized chemical co-precipitation methods. LDH then applied as adsorbent for arsenic removal from synthetic acid mine drainage. characterizations of SEM and XRD analysis showed that had many different functional groups a high specific surface area adsorption processes. morphological structure by SEM-EDS method shows round shape with particle size about 1 μm, XRF Mn Fe elements dominate more than other components. Batch experimental conducted an to study effect contact time, equilibrium pH, temperature on removal. uptake capacity selectivity ion exchange between anions As (V) solution main mechanism. Therefore, can be used water wastewater treatment. In contrast, this research has potential processed developed into advanced materials.
