APPLICATION OF RESPONSE SURFACE METHODOLOGY AND DESIRABILITY FUNCTION IN THE OPTIMIZATION OF ADSORPTIVE REMEDIATION OF ARSENIC FROM ACID MINE DRAINAGE USING MAGNETIC NANOCOMPOSITE: EQUILIBRIUM STUDIES AND APPLICATION TO REAL SAMPLES

Molecules 24:1792(2019)

This study tested the effectiveness of magnetic multi-walled carbon nanotube/zeolite nanocomposites to adsorb and remove arsenic ions in simulated and real acid mine drainage samples. Adsorption studies demonstrated that the nanoadsorbent can remove arsenic in simulated samples within 35 min. After separation from the solution, the nanoadsorbent was washed in a 0.05 mol/L HCL solution for regeneration, and was reusable for at least 10 cycles of adsorption-desorption with no significant decrease in the adsorption capacity. The nanoadsorbent was also used for the arsenic removal from acid mine drainage. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6539454/pdf/molecules-24-01792.pdf
