摘　　要：通过对脱墨浆 (主要是旧新闻纸脱墨浆 )漂白的研究 ,探求获取高白度漂白脱墨浆的途径。结果表明 ,采用螯合剂预处理的H2 O2 FAS两段漂白效果优良 ,白度增值达到 1 1 . 9%ISO ,浆料最终白度可达 66 . 6 %ISO。The bleaching of deinked pulp (mainly ONP deinked pulp) was studied in this paper in order to find a way for producing a bleached deinked pulp with high brightness.The results showed that the chelating-H_2O_2-FAS bleaching sequence had optimum performances,and the final brightness of the bleached deinked pulp reached 66.6%ISO with 11.9%ISO brightness gain.
