Scholarcy highlights

  • The aim of this study is to synthesize the three different hybrid materials precursor to natural biopolymer chitosan
  • The silanes viz., 3-mercaptopropyl trimethoxysilane, trimethoxy(octyl) silane and 3-aminopropyl triethoxysilane were grafted with the chitosan network and were named as CHMS, CHTS and CHAS, respectively
  • The materials were characterized by the FT-IR spectrometry, SEM–EDX and XPS analyses
  • An increase in background electrolyte concentrations from 0.0001 to 0.05 mol/L NaNO3 was assessed for the uptake of Cr(VI) by these hybrid materials
  • A detailed sorption mechanism was included with the help of FT-IR, TOC and XPS analyses
  • CHMS and CHTS were used for dynamic studies under column reactor operations
  • SEM micrographs of Chitosan CHMS CHTS and CHAS and the applications of hybrid materials in the batch and column reactor operations
