## 1 Introduction  
The scope of our work is to describe the transport properties with existing models without any additional data. Moreover, the gas separation mechanism for GO membranes is unclear due to inconsistent permeation and separation results reported in the literature. It is known that graphene-based materials are very efficient in many areas of chemical engineering in particular for the elaboration of new type of batteries for modern electronics [1] and for creation of new types of membranes for the separation of gas mixtures [2]. Graphene is a two-dimensional one-atom-thick sheet of carbon atoms packed in the honeycomb crystal lattices, it is characterized by unique physicochemical properties in particular the high chemical stability, mechanical strength, thermal conductivity and charge mobility [1, 2]. It was shown that pristine graphene is impermeable in regard to smallest molecules [2]. A graphene sheet with nano and sub-nano pores, known as nanoporous graphene (NG), is used for the size-selective separation of gas mixtures based on the molecular sieving effect [2]. The permeability and selectivity of NG membranes are higher than the aforementioned values for polymer membranes. Ion bombardment and electron beam exposure are often used to prepare pores in the graphene sheets. As indicated in [3], molecules adsorbed on the graphene sheet and participating in surface diffusion [4] are more likely to find the pores in NG membranes than the gas molecules. Thus, surface diffusion can be one of the main processes affecting the transport of gas molecules through NG membranes [5, 6, 7]. It should be noted that the problem related to the management of the transport of gas molecules using the porous graphene is very actual (e.g., for removing carbon dioxide from the gas mixtures) [8]. The core factor affecting permeance of NG membranes is the pore size. However, as indicated in the aforementioned paper, it is difficult to fabricate defect-free porous membranes in a large scale that have pores matching the kinetic diameters of common gas molecules, ranging from 2.5 to 4.0 A. The combined use of the ionic liquid and porous graphene for more effective separation of the gas mixtures is considered in [8]. It is demonstrated from classical molecular dynamics simulations that a monolayer of ionic liquid on the NG membrane can be used to control the pore size of porous graphene. However, this method requires modification of the original membrane. In the present paper is discussed the new method to control the gas transport through NG membranes using external fields (e.g., resonance laser radiation) leading to excitation of gas molecules and changing their interaction with the graphene sheet. In this case do not need any modifications of the original membrane. The effect of resonance radiation on the separation of the gas mixtures passing through the dense membranes was considered in [9]. Graphene oxide (GO) can be considered as the oxidized form of graphene [2]. GO membranes contain stacked GO sheets as well as vacancy defects and functional groups distributed in carbon lattice, these membranes can be cheaply produced by oxidation and exfoliation of graphite [2]. The problems related to preparation of GO membranes and mass transfer in them were discussed in particular in [10; 11; 12]. In [10] it was shown that self-standing GO membranes demonstrate outstanding performance for hydrogen separations, including mixtures of H\({}_{2}\)/CO\({}_{2}\) and H\({}_{2}\)/hydrocarbons. An efficient spray-evaporation method was explored in [11] to optimize performance of GO membranes. The very interesting experimental results related to the transport of gases such as CH\({}_{4}\), N\({}_{2}\), CO\({}_{2}\), H\({}_{2}\) and He through GO membranes are given in [12]. These results can be used in a study of the separation of gas mixtures and in a development of new models for mass transfer through GO membranes.
