Abstract
The present study highlights the potential application of electrospun polyacryloni-trile/metal salts (CrO3, CuCO3) nanofibrous filter media impregnated with TEDA (PAN-M-TEDA) as an efficient adsorbent for hydrogen cyanide removal from air. The PAN-M-TEDA nanofiber before and after adsorption of hydrogen cyanide was characterized with Fourier transforms infra-red microscopy (FTIR). The concentration of hydrogen cyanide passes through the samples was determined by measuring the absorption of hydrogen cyanide in the solution containing indicator via UV-Vis spectroscopy. The results showed that introducing metal salts to PAN nanofiber along with their impregnation with TEDA, significantly increases the adsorption capacity of nanofibrous filter media. The adsorption of hydrogen cyanide over PAN-M-TEDA nanofiber was also studied as a function of thickness, PAN concentration and TEDA concentration by response surface meth-odology (RSM) based on central composite design. It is found that the highest adsorption capacity can be achieved at thickness 28.42 mm, PAN concentration 16.19 w/v % and TEDA concentration 14.80 w/v %.
