Abstract
The effect of bleaching and bleach stabilization chemicals deposited o n an aluminosilicate support has been investigated on the optical prop el;tics of recycled ONP in repulper as well as in bleaching bag. The a dvantage of incorporating bleach chemicals as releasable impregnates o n sodium A type zeolite has been discussed. Zeolite support has a syne rgistic effect on bleach stabilization of recycled ONP with phosphorou s and organic acid -based chemicals. Role of zeolite support in min re tention and white-water quality is also discussed.
