Abstract

In this study, the oxidative delignification and bleaching of alkaline sulphite-anthraquinone (AS/AQ) wheat straw pulp is reported.
Oxygen, oxone and hydrogen peroxide were used to achieve targeted brightness > 80 % ISO without compromising the other pulp
properties i.e., burst, tensile and tear index, kappa number, CED viscosity, hexenuronic acid, accelerated ageing and percentage yield of
bleached pulp. The effect of various reaction parameters such as alkali, pulp consistency, temperature, time and bleaching agent dosage
were optimized for each stage of bleaching.
