Manganese(II) removal from aqueous solutions by adsorption on drinking water treatment sludge
Water treatment plant (WTP) sludge was used as a low-cost adsorbent for manganese (Mn(II)) removal from aqueous solutions. The sludge was subjected to thermal treatment (80–500 °C) and chemical activation with KOH to enhance its physicochemical properties. The activated material exhibited increased porosity and surface...
