Predicting Microwave Complex Dielectric Constant of Water-Surfactant Mixtures
Subject area: Science,Engineering and Technology · Area of research: Chemical Engineering
Abstract
Low dielectric constant, low conductivity surfactant X-100 was mixed with deionized water to form mixtures that had a wide range of complex permittivity. Two parallel mixing rules were used to predict thecomplex dielectric properties of the mixture in the microwave frequency range: a simple 2-component mixing rule and a 3-component mixing rule in which water was treated as comprised of free and bound waters. Experimental results show that the incorporation of bound water into the mixing rule improves the prediction to a great extent. A diagram to help predictingthe bound water fraction for the mixture is also given in this paper.
