The respon.es evaluated were the pulp yield, cellulose con.en., an. the degree of delign.fication. Various regression.m.dels were used to evaluate the effects of varyin. the pulpin. con.ition.. The optim.m.con.ition. attain.d were;n.OH charge of 14.63%, 0.1% an.hraquin.n., an. a pulpin. period of 154 m.n.tes, correspon.in. to 20.68% pulp yield, 80.56% cellulose con.en., an. 70.34% lign.n.rem.val.
