文摘
- •
Polyscrylonitrile (PAN) nanofibers prepared through electrospinning and chemically modified with ethylenediaminetetraacetic acid using ethylenediamine crosslinker.
- •
Fabricated nanofibers have enhanced surface chemistry with insignificant impact on the nanofibrous structure.
- •
Excellent maximum adsorption capacities of 66.24 and 32.68 mg g−1 toward Cr and Cd ions, respectively.
- •
A pre-concentration factor of 19 achieved for removal of Cd and Cr in environmental water samples.
