磷矿捕收剂油酸钠的表面张力研究

Research on the surface tension of phosphorus ore collector—sodium oleate

通过滴体积法测定了不同温度、pH和盐浓度等条件下油酸钠水溶液的表面张力,测定了油酸钠-吐温80复配体系水溶液的表面张力,初步研究了油酸钠的表面活性以及吐温80对油酸钠的增效作用,为选矿作业提供了理论支持。

Sodium oleate is one of most important phosphorus ore collectors,and the importance of research on the surface tension of sodium oleate is self-evident.In this paper,we determine the surface tension of the aqueous solution of sodium oleate with drop volume method under different temperature,pH and salt concentration;we also determine the surface tension of sodium oleate-tween 80 mixed system,and then we initially study the surface activity of sodium oleate and the synergism effect of tween 80 to sodium oleate.Through the research,we provided theoretical basis for phosphorus ore floatation.
