چکیده | ||
SBA-15 grafted with N-(4-(trimethylsilyl) butyl)-9H-fluorene-9-amine was synthesized by a simple strategy and applied to removal of Acid Red 33 and Acid Black 194 from aqueous solutions. SBA- 15 was synthesized and Functionalized according to procedure in the literature. Fluorene functionalized SBA-15 was showed the BET surface area 200 m2g-1 and pore diameter 4.2 nm, based on adsorption-desorption of N2 at 77 K. The presence of organic groups in the silica framework was demonstrated by FTIR and Raman spectrum. The effects of pH, amount of adsorbent, contact time and dye concentration on adsorption were determined in order to find the optimum adsorption conditions. The data fitted well to the Langmuir model with maximum adsorption capacities 500.0 mg/g for Acid Red 33 and 110.0 mg/g for Acid Black 194. The results were shown that this methodology could be suitable for the removal of the pollutant acid dyes from dyeing wastewater of handmade carpet’s fibers. | ||
