摘　　要：由于传统容量分析方法操作繁琐,再现性差,误差较大,通过理论分析与对比试验,尝试用电位滴定法对硫酸盐法制浆黑液残碱的测定方法和条件进行探索,建立可操作的测定方案,达到了取代传统容量分析方法准确快速指导生产的目的。Because the traditional capacity analysis operation trival, reproducibility is poor, error is bigger, by using the ways of theoretical analysis and contrast test, this paper tries to explore the measurement method and conditions of kraft pulping black liquor residual alkali by using the potentiometric titration, and establish workable determination solutions, to achieve the purpose of replacing traditional eapacity analysis method and guide the production purposes quickly and accurately.
