Highly sensitive, accurate and relatively fast technique has been utilized to remove reactive red 198 (R.R. 198) dye in textile wastewater, using synthesised nanocomposites. Determination of R.R. 198 dye was carried out by UV-Vis spectrophotometer at λmax= 515 nm. A SBA-15 mesoporous silica was synthesized then was functionalised using dodecyl trimethyl ammonium chloride (DOTAC) cationic surfactant. TEM, elemental analysis CHNS, TGA, FT-IR, and BET techniques were used to characterize the nanocomposites features. This research studies the impact of various parameters in removal of R.R. 198 dye by nanocomposite, like pH, quantity of nanocomposite, contact time, type of eluting solvent, and concentration of R.R. 198 dye was investigated. Experiments show that the new nanocomposite (DOTAC/SBA-15) is an excellent and powerful nanocomposite for removing the R.R. 198 dye from textile wastewater such as, Mazandaran textile factory, Qaemshahr sangtab textile factory, Amol babakan textile factory and Behshahr Acryltab factory with suitable fallouts.
