开发了一种研究乳液稳定性的新技术。由于乳液浊度是颗粒浓度和尺寸的函数，因此可以通过测量浊度随时间的变化来确定乳液的稳定性。浊度与粒径和浓度之间的关系是针对多分散乳液得出的。将通过测量初始平均粒径和乳液浊度变化确定的声学制备乳液的稳定性与通过扫描电子显微镜测量颗粒生长速率确定的稳定性进行比较。两种方法之间的一致性非常好。
A novel technique for studying the stability of emulsions has been developed. Owing to the fact that emulsion turbidity is a function of particle concentration and size, the stability of emulsions can be determined by measuring the change in turbidity with time. The relationship between turbidity and particle size and concentration is derived for a polydispersed emulsion. The stability of acoustically prepared emulsions determined by measuring the initial mean particle size and changes in emulsion turbidity is compared with the stability determined from scanning electron microscope measurements of the particle growth rate. The agreement between the two methods is excellent.
