摘　　要：造纸厂制浆黑液的残碱都是采用酸碱中和滴定(容量法)测定,该文改用电位滴定法测定制浆黑液中的碱的方法进行探索和对沉降剂进行选择,建立可操作的初步测定方案。residual alkali in paper pulp black l iquor is usually measured with acid -base titra-tion.This paper introduces potentiometeric titration as an alternativ e.The author also tries to choose a different kind of precifitating age nt and set up a feasible preliminary measurement project.
