A Kinetic Study Using Evaporation of Different Types of Hand-Rub Sanitizers
Pinhas, Allan R.
Journal of Chemical Education, v87 n9 p950-951 Sep 2010
Alcohol-based hand-rub sanitizers are the types of products that hospital professionals use very often. These sanitizers can be classified into two major groups: those that contain a large quantity of thickener, and thus are a gel, and those that contain a small quantity of thickener, and thus remain a liquid. In an effort to create a laboratory experiment that is relevant to nursing students and other allied health students taking a general-organic-biochemistry (GOB) course, the rate of mass loss due to evaporation of two different types of alcohol-based hand-rub sanitizers has been developed into a kinetics experiment. It was found that the gel has a slower rate of evaporation than the liquid. When the data are plotted using first-order kinetics, a straight line is obtained for each type of sanitizer.
