Carboxylmethyl konjac glucomannan conjugated polydopamine composites for Pb(II) removal

Carboxylmethyl konjac glucomannan conjugated polydopamine (CMKGM-PDA) composite was successfully prepared using a cost-effective method. CMKGM-PDA exhibited excellent adsorption performance for the removal of Pb(II) and could be a convenient agent for recovery. The Langmuir linear model was suitable for describing the adsorption process of Pb(II). The maximum adsorption capacity was 95.24 mg g−1 at 298 K, showing a high absorption capacity in...
