Graft efficiency
WebIn the absence of acid, no grafting on wool was determined most probably because [Ce-O-Ce]6+, which is the hydrolysis product of Ce 4+ ions, could not form a complex with wool [22]. Since the grafting efficiency of Ce ion in neutral medium is low [23], it is used together with an acid, mostly nitric acid (HNO 3).
