Simultaneous removal of Pb2 Cu2 Zn2 and Cd2 from

The pH of the aqueous metal-ion solution plays an important role in the adsorption process of heavy metals onto clay minerals. Simultaneous adsorption of Pb 2 Cu 2 Zn 2 and Cd 2 using the Mt–K m Mt–K/TiO 2 c and Mt–K/TiO 2 a was studied at varying pH values from 2.0 to 6.4.The results obtained for Pb 2 and Zn 2 ions were shown in panels a and b respectively in Fig. 1
