文摘内容 Bleaching of poplar APMP with Formamidinesulphinic acid (FAS) was investigated in this paper.The effects of FAS charges, ratio of treatment on thebrightness gain, color reduction and pulp strengthwere studied. A single-stage FAS bleaching wasoptimized. Under the conditions of 10 % pulpconsistency, 60 minutes time and 70~C reactiontemperature and 0.6 %, FAS (on 0.d.pulp), ratio ofFAS to NaOH was 2, we produced a bleached pulpwith a brightness of 62.3 %(SBD), a brightness gainof 9.2 units。
