摘要
用分光光度法研究水中金属离子浓度、pH值和添加不同种类表面活性剂等对松香皂乙醇水溶液稳定性的影响,并寻找提高松香皂乙醇水溶液稳定性的方法。实验结果表明:在实验研究的离子浓度范围内(Ca2+浓度0～0.78mmol/L、Mg2+浓度0～0.74mmol/L),水的硬度对松香皂乙醇水溶液稳定性没有影响;在偏碱性的水溶液中加入适量非离子表面活性剂可有效提高松香皂乙醇水溶液的稳定性。
This paper studies some factors such as the concentration of metallic ion in water,pH and addition of some surfactants which affects the stability of a rosin soap in alcohol/water solution and also tries to find out the way which can improve the stability of the rosin soap.The results reveal that the water rigidity is no any effect to the stability of the rosin soap in alcohol/water solution,and in alkaline water solution the stability of the rosin soap in alcohol/water solution could be improved by adding some non-ionic surfactants properly.
