Similar research on the imidazole functional groups incorporated into nitrilon
fibers was carried out by Gong [43]. The ion exchange capacity as well as desorption
conditions (4 mol L –1 HCl + 3% NH 2 CSNH 2 ) were defined for Au(III), Hg(II) and
Pd(IV) ions (2.92 mmol Au(III) g –1 , 1.81 mmol Hg(II) g –1 , 1.56 mmol Pd(IV) g –1 )
in the column system. Because of high recovery factors of these ions (96.5–100%)
during multiple application, the fibers (Fig. 19) can find practical application in their
sorption.
