Using the principles of gas adsorption kinetics, we have developed a new theoretical model addressing the adsorption and breakthrough of contaminant vapors or gases with respect to solid sorbents. Specifically, we have applied the theory to predict respirator cartridge service life in connection with individual contaminant exposure to toluene, vinyl chloride, ethyl acetate, and each of several different trichlorinated hydrocarbons at several levels of concentration. Theoretical expressions and contaminant breakthrough curves derived from our new approach are compared with those published previously by Mecklenburg and by Wheeler. The breakthrough curves derived by Mecklenburg and by Wheeler have approximately the same shape as the corresponding experimental curves for 0% to 40% breakthrough. However, these curves deviate in varying degrees from the experimental data at breakthrough values exceeding 40%. By contrast, our new theory agrees with published experimental results over the entire range of 0% to 100% breakthrough. The new model not only agrees with experimental observation, it is also less complicated and easier to apply to practical industrial hygiene problems than theories developed previously.
运用气体吸附动力学原理，我们开发了一种新的理论模型，用于解决污染物蒸气或气体在固体吸附剂上的吸附和穿透问题。具体而言，我们已将该理论应用于预测防毒面具滤毒罐的使用寿命，该滤毒罐用于应对个体接触不同浓度水平的甲苯、氯乙烯、乙酸乙酯以及几种不同的三氯代烃。我们新方法得出的理论表达式和污染物穿透曲线与梅克伦堡和惠勒之前发表的结果进行了比较。梅克伦堡和惠勒得出的穿透曲线在0%至40%穿透率范围内与相应的实验曲线形状大致相同。然而，在穿透率超过40%时，这些曲线与实验数据存在不同程度的偏差。相比之下，我们的新理论在0%至100%穿透率的整个范围内都与已发表的实验结果相符。新模型不仅与实验观察结果一致，而且比之前开发的理论更简单，更易于应用于实际工业卫生问题。
