RESUMO
The cyclohexane is the common toxic volatiles emitted from the various industry in worldwide leading to environmental degradation and human illnesses. Hence, there is a requirement for an efficient and stable adsorbent for adsorbing these toxic molecules to safeguard human health and the air atmosphere. Hollow carbon spheres (HCS) are a new type of carbon nanomaterial with large specific surface area, low density, and good chemical and thermal stability. In this study, DFT simulations and static-dynamic adsorption studies of cyclohexane were carried out using HCS as the adsorbent material. Among them, static adsorption focuses on adsorption/desorption isotherm, adsorption isotherm model fitting and isosteric heat of adsorption. Dynamic adsorption was mainly studied the effect of initial concentrations, gas flow rate, and ambient temperature on adsorption performance. The results showed that HCS exhibited very good performance in cyclohexane adsorption.
