چکیده مقاله
The present study describes the synthesis of a nanosorbent for elimination of hinosan from underground water The nanosorbent consists of polyacrylonitrile/carbon nanotube PAN/CNT nanofiber with high extraction capacity and good capacity for adsorption of hinosan was prepared in a single fluid solution and synthesized through electrospinning strategy The nanosorbent was characterized using Fourier transform infrared spectroscopy FT IR , scanning electron microscopy SEM and transmission electron microscopy TEM , and the quantification of hinosan was carried out by gas chromatography electron capture detector GC ECD To achieve maximum extraction performance, the influential parameters on the extraction efficiency were surveyed Kinetic of adsorption was studied, and Langmuir and Freundlichʹs models were applied to describe the characteristics of adsorption behavior The equilibrium data were well fitted to the Langmuir isotherm model and based on the Langmuir isotherm model; the maximum adsorption capacity is 88 35mg/g Based on the kinetics investigation, it was found that the data were well fitted with the pseudo second order kinetic
