To MOW chemical and enzyme deinked pulp, wire-blotter difference of specimen prepared using buchner funnel procedure, distilled water, adding PAM and Al_2(SO_4)_3 was the least and retention of ink particles was the highest.

• 而对于MOW化学脱墨浆和MOW酶法脱墨浆,采用布氏漏斗,用去离子水,添加PAM和Al_2(SO_4)_3抄片时,所得浆片的两面差很小,白度最低,尘埃度及残余油墨浓度最高,油墨粒子的留着率最高。
