Removal of Cd(II) and Pb(II) from aqueous solution by modified attapulgite clay
Three low-cost adsorbents (purified raw attapulgite (A-ATP), high-temperature-calcined attapulgite (T-ATP), and hydrothermal loading of MgO (MgO-ATP)) were prepared as adsorbents for the removal of Cd(II) and Pb(II).By evaluating the effect of the initial solution pH, contact time, initial solution concentration, temperature and coexistence of meta
