Iron-carbon composite from carbonization of iron-crosslinked sodium alginate for Cr(VI) removal

It is vital to prepare iron (Fe)-containing porous carbonaceous materials (Fe/C) with high reductive Fe content, large specific surface area, and abundant oxygen-containing functional groups to alleviate the toxicity and mobility of Cr(VI) from both reduction and adsorption. In this study, Fe-crosslinked sodium alginate (SA-Fe) was carbonized to prepare an Fe/C composite (SA-Fe-C) with high content of reductive Fe content for Cr(VI) removal via...
