Correlation between the solid/air partition coefficient and liquid molar volume for VOCs in building materials

A correlation between partition coefficients, K, of dry building material and liquid molar volume of volatile organic compounds (VOCs) in it, vl, is presented. Experiment for determining the partition coefficients of the target VOCs including benzene, toluene, ethylbenzene for two kinds of building materials was conducted by a method developed by us. The experimental data verified the correlation. Also the correlation was supported well by the experimental data in the literature. It is found that the correlation can predict the partition coefficients of VOCs with similar structure in the same building material.
