阴离子分散剂Lomar Pw中Na2SO4含量的测定
Measure the Na2SO4 in Electronegationeion Dispersant Agent
【摘要】 用热的二甘醇使Na2SO4从Romar PW中分离出来,然后用BaCl2沉淀SO42-,重量法测定Na2SO4含量。本方法排除了干扰因素,准确度、精密度高,实用性强。
【Abstract】 With the hot diglycol, Na2SO4 is removed from the Lomar Pw,then Na2SO4 will be measured with gravimetric method that BaCl2 prelipitaties SO42-. The method has no interference. Accuracy and prelision are higher than other.
