“…Some of the similar investigations related with this study are summarized as follows. George et al investigated the adsorptions of Co(II), Ni(II), Cu(II) and Zn(II) ions onto the N,N -methylenebisacrylamide cross-linked polyacrylamide and glycine attached divinylbenzene structures, and they reported that the maximum Cu(II) ion adsorption could be achieved at 2.5 h [19]. Shreedhara-Murthy and Ryan investigated uranium, mercury, copper, cadmium and lead ions adsorption onto the cellulose dithiocarbamate resin and they reported that the maximum adsorption value could be achieved in a very long time [20].…”
