一些研究人员研究了有机溶剂通过化学防护手套的扩散，并使用各种模型估算了扩散系数。在本研究中，使用 ASTM F-739 标准测试方法进行了苯、甲苯和苯乙烯通过丁腈橡胶和氯丁橡胶手套的渗透实验。使用文献中的几个模型来估计扩散系数。利用基于菲克第二定律的一维扩散方程和估计的扩散系数，模拟渗透浓度并与实验结果进行比较。建模结果表明，通过浸泡测试获得的手套材料中溶剂的溶解度并不是有机溶剂渗透聚合物手套的合适边界条件。这项研究的建模工作将帮助工业卫生学家评估工人通过化学防护手套接触到的化学品。
Several researchers have studied the diffusion of organic solvents through chemical protective gloves and have estimated the diffusion coefficients by using various models. In this study, permeation experiments of benzene, toluene, and styrene through nitrile and Neoprene gloves were conducted using the ASTM F-739 standard test method. The diffusion coefficients were estimated using several models from the literature. Using a one-dimensional diffusion equation based on Fick's second law and the estimated diffusion coefficients, the permeation concentrations were simulated and compared with the experimental results. The modeling results indicated that the solubility of the solvent in the glove materials obtained by immersion tests was not an appropriate boundary condition for organic solvent permeation through the polymer gloves. The modeling work of this study will assist industrial hygienists to assess exposure of chemicals to workers through the chemical protective gloves.
