摘要

The activation energy of a liquid molecule and hence its viscosity coefficient changes with addition ofudcontaminants to the original liquid. This forms the basis of a new technology for analysis of purity of the liquid.udWe discovered that concentration of certain contaminants such as water in alcohol or vice versa can be uniquelyudand accurately determined in a short time (about 10-15 minutes) using a simple and yet innovative technique thatudonly requires measurement of time of flow of the impure liquid (say, water-alcohol mixture) and distilled waterudthrough a simple viscometer designed and constructed for this purpose. We find that the viscosity coefficient μ ofudalcohol increased almost linearly with water concentration at a rate that depends on the type of alcohol and waterudconcentration. We determined the increase of activation energy of alcohol molecules with increase of waterudconcentration. This increase also depends on type of alcohol. Our detailed investigation on alcohol-waterudmixtures for both ethyl and methyl alcohol along with discussion on possible future potential application of suchuda simple, yet very reliable inexpensive technique for liquid purity analysis is presented. A comparison is made ofudour present method with other methods on the accuracies, problems and reliability of impurity analysis. A part ofudthe quantum theory of viscosity of liquid mixtures that is in the developmental stage in order to explain some ofudthe observed properties is presented.
