Ionic silica based hybrid material containing the pyridinium group used as an adsorbent for textile dye

► Ionic silica containing the pyridinium group was employed for the adsorption of RR-194 dye. ► Three samples were prepared varying the molar inorganic percentage. ► The materials were characterized by spectroscopic and thermogravimetric analyses. ► The higher surface area of the hybrid material leads to higher % of dye removal. ► Simulated dye-house effluent was treated with hybrid adsorbent materials.
