Dimethyl disulfide (DMDS) has a specific unpleasant odour and is profoundly toxic with an odour threshold of around 7-12 ppb. In this study, the removal of DMDS was investigated by adsorption on activated carbon cloth (ACC) in the gas phase. Kinetics and isotherm studies were performed. Adsorption kinetics followed by GC-MS and the data were processed using different models. When correlation coefficients (R) of linear regression analysis are analyzed, it is seen that the concordance of experimental data to the pseudo-second-order equation is quite good. Isotherm data have been examined using Freundlich, Temkin and Langmuir models. The regression coefficient (R) of data to fit the Langmuir model is 0.9993, which means that the fit is very good. The monolayer adsorption capacity (q) of DMDS has been calculated as 118 mL.g according to the Langmuir model.
二甲基二硫醚（DMDS）具有特殊的难闻气味，毒性极强，其气味阈值约为7 - 12 ppb。在本研究中，对气相中活性炭布（ACC）吸附去除DMDS进行了研究。进行了动力学和等温线研究。通过气相色谱 - 质谱联用仪跟踪吸附动力学，并使用不同模型对数据进行处理。分析线性回归分析的相关系数（R）时，可以看出实验数据与伪二级方程的一致性相当好。已使用弗伦德里希、坦金和朗缪尔模型检查等温线数据。数据拟合朗缪尔模型的回归系数（R）为0.9993，这意味着拟合效果非常好。根据朗缪尔模型，DMDS的单层吸附容量（q）计算为118 mL·g。
