在不同环境条件（空气温度、相对湿度和空气速度）下使用小型环境室获得的吸附数据已用于评估不同建筑材料对VOC吸附的线性朗缪尔模型和扩散模型。根据ASTM推荐的统计指标，通过模型曲线拟合实验数据的优度和基于吸附期数据预测解吸期的能力，对这两个模型进行了评估（1）。线性朗缪尔模型似乎适用于涂漆干墙和天花板瓷砖，而扩散模型似乎更适用于地毯。吸附模型参数的变化并不总是与环境条件的变化一致。单位: （啜泣）阿什雷交易，第109卷，第。1

Sorption data obtained by using small environmental chambers under different environmental conditions (air temperature, relative humidity, and air velocity) have been used to evaluate the linear Langmuir model and the diffusion model for VOC sorption by different building materials. The two models were evaluated (1) by the goodness of model curve-fitting to the experimental data according to the ASTM recommended statistical indices and (2) by the ability in predicting the desorption period based on the data from the adsorption period. The linear Langmuir model appeared to be suitable for the painted drywall and ceiling tile while the diffusion model seems more suitable for carpet. The variations of the sorption model parameters are not always consistent with the changes of the environmental conditions.Units: SI
