Hierarchically structured polyacrylonitrile nanofiber mat as highly efficient lead adsorbent for water treatment

Diameter effect of electrospun carbon fiber support for the catalysis of Pt nanoparticles in glucose oxidation

“…After 450°C, a significant decrease in the weight was observed and the curve reached an inflexion point at 450°C, where the remaining weight ascribed to Pt nanoparticles was 60.26%. Interestingly, a similar change was observed in Pt/CF 158nm and Pt/CF 309nm , but the thermal decomposition temperatures of CF 158nm and CF 309nm were 630°C and 628°C, respectively, approaching 682°C for the complete degradation of pure PAN CFs [34]. The CFs with larger diameter needed a higher decomposition temperature.…”

Chitosan nanofibers functionalized by TiO 2 nanoparticles for the removal of heavy metal ions

“…The maximum sorption capacities of Pb (II) and Cu (II) ions onto the chitosan/TiO 2 nanofibrous adsorbents were compared with that of the other nanofibrous adsorbents which results are presented in Table 4. As shown, the sorption capacities of both chitosan/TiO 2 nanofibrous adsorbents were found to be comparable and moderately higher than those of many corresponding sorbents in the literature [ [13,16,[29][30][31][32][33][34][35][36].…”

Preparation of α-Fe2O3/polyacrylonitrile nanofiber mat as an effective lead adsorbent

“…For example, high adsorption of heavy metal ions including Pb 2+ was observed in electrospun nanofiber mats of chitosan, polyacrylonitrile (PAN) and polyethylene mine (PEI), suggesting that nanofiber mats have great potentials in water purification application [25][26][27][28] . Our previous work, has demonstrated the electrospun PAN nanofiber mats modified by amine group or metal oxide were highly efficient in adsorbing of Cu 2+ and Pb 2+ [29][30][31] from aqueous solutions, suggesting that the PAN nanofibers could be excellent adsorbents used in heavy metal removal. Various studies have been reported the formation of Fe 2 O 3 [32][33][34] .…”
