The object of this study was to investigate the permeation of organic solvent mixtures through Nitrile and Neoprene protective gloves. Diffusion coefficients and solubility of organic solvents, such as benzene, toluene, ethyl benzene and p-xylene, were estimated by ASTM F739 permeation experiments and Fick’s Law. This study can be a fundamental work to assess the exposure of chemical mixtures as labors wearing the protective gloves for different processes.
The break through time and steady state permeation rates of pure solvents were found to be significantly correlated to their octanol-water partition coefficients. The results of mixture organic solvents can be interpreted using the solubility parameter theory. The organic solvents and gloves have the similar solubility parameters, and the organic solvent maybe dissolved into the gloves. This can be resulted in a greater permeation rate and shorter break through time.
For organic solvents mixtures, the steady state permeation rate and solubility were correlated well to their mole fractions. The diffusion coefficients were not constants and dependent on their mole fractions. The one-dimensional transient model was able to simulate the permeation concentrations and implied that equilibrium partition between organic solvent and gloves was not achieved during the initial permeation.
