表面活性剂L-113A增溶能力的测定

Determination of Solubilization Ability of Surfactant L-113A

采用分光光度法研究高分子表面活性剂L-113A的增溶能力,用一定量的表面活性剂将苯增溶在水中,当体系中苯的含量超过表面活性剂的增溶极限时,便产生浑浊,溶液光密度迅速增大,由此来测定表面活性剂的增溶能力。由实验得出在溶液含苯量最小时就已经超过了表面活性剂的增溶极限,因此表面活性剂L-113A几乎没有增溶能力。

Solubilization ability of surfaetant L- 113A was studied with spectrophotography. The quantum of surfaetant L- 113A dissolved benzene in Aqueous solution, when benzene in the system exceeds the maximum of solubilization of the suffactant, It will be muddy and light - density of the solution will rapidly raise. The less content of benzene in the solution has exceed the limit of solubilization of surfactant L - 113A, so it hasn＇t almost the ability of volume swelling.
