摘要
两相含水有机介质中电导滴定法测定接木浆中酚羟基和羟基的方法是可行的。较好的滴定条件是：滴定介质为丙酮：吡啶：乙醇：水（40：10：1：1，体积比）；样品浓度为2g/L，滴定剂KOH-异丙醇浓度为0．01mol/L。
The contents of phenolic hydroxyl and carboxyl groups in kraft pu;p from Eucalyptus were determined in a heterogeneous system by conductometric titration .The samples were dis-persed in a mixed medium at 25C. Recommended solvent composition was:acetone/pyridine/al-cohol/water （40／10／1／1， V／V／V／V）．0．01mol/L KOH－ iso －propanol solution was used as the titrant. Suitable sample concentration was no more than 2g/L.This method was proved to be feasible and accurate.
