- ... This study describes an efficient adsorbent consisting of magnetic Fe₃O₄ and gellan gum, which couples magnetic separation with ionic exchange for heavy metal removal. Adsorption kinetics analysis showed that the adsorption capacities were in an order of Pb²⁺ >Cr³⁺ >Mn²⁺. Different experimental parameters studies indicated that adsorbent dosage, initial metal concentration, temperature and initial ...
