木质素胺的电导滴定

Conducometric Titration of Lignin-Amine

分别以不同浓度的十二烷基硫酸钠对各木质素胺水溶液进行电导滴定,并根据十二烷基硫酸钠的反应量及溶液电导率的变化,可确定滴定终点,从而能够对各木质素胺样品的改性率程度进行比较。

The conducometric titration of different concentration of lignin - amine solution was studied with different concentration of sodium,laury sulfate（SDS）. The end points of titration can be determined through the change of conducomentric curve, and achieve the modification rate of the modified lignin.
