AB  - A novel, inexpensive and eco-friendly aminated lignin/geopolymer supported with 
      Fe nanoparticles (Fe@N-L-GM) composite was successfully synthesized using kaolin 
      and lignin as the major precursors. The prepared Fe@N-L-GM had larger specific 
      surface area, rich oxygen-containing and nitrogen-containing functional groups, 
      greater electron transfer ability and interconnective porous structure. The 
      Fe@N-L-GM could be employed as the adsorbent of Cr(VI) and the activator of 
      potassium peroxymonosulfate (PMS) for treatment of Cr(VI) and naphthalene (NAP) 
      in wastewater. The adsorption and degradation results indicated that the maximum 
      adsorption capacity of Cr(VI) could reach 65.83 mg g(-1), whereas the maximum NAP 
      degradation efficiency could reach 97.81 %. The adsorbed Cr(VI) was mostly 
      converted to the low toxic Cr(III) through the reduction of electron donors such 
      as Fe(II), amino and hydroxyl groups. The quenching experiment results confirmed 
      that .OH might be the crucial ROSs in mediating NAP degradation. In the 
      simultaneous removal experiment of Cr(VI) and NAP, the Cr(VI) removal rate was 
      significantly improved in the presence of NAP, while phenol as the degradation 
      intermediate of NAP might be the main substance for promoting the reduction of 
      Cr(VI). This work provided the theoretical foundation and a new type of material 
      for the simultaneous removal of heavy metal and persistent organic pollutants 
      (POPs).
