摘　　要：研究了Na2SO3与DTPA联合用于废报纸脱墨浆H2O2漂前预处理的效果,并与尿素、DTPA、硫酸、EDTA预处理剂的预处理效果进行了比较。结果表明,Na2SO3与DTPA联合是种优良的预处理剂,与其他预处理剂相比,可使漂后浆白度提高1.4%～4.2%ISO。This paper investigates the optimal condition of Na2SO3 and DTPA pretreatment prior to H2O2 bleaching of ONP deinked pulp and compares the effect of NaESO3 and DTPA pretreatment with CO（NH2）2, DTPA, H2SO4, EDTA pretreatments in their optimal conditions. Results indicate NaESO3 and DTPA as a very good pretreatment agent of ONP deinked pulp bleaching is clearly proved, the delignified pulp brightness increase by 1.4%～4.2%ISO.
