Abstract
Ispitana je adsorpcija kvarternog amonijevog surfaktanta; heksadeciltrimetilamonijevog (HDTMA) bromida na sintetski zeolit mordenit. Ispitano je i bistrenje sintetske otpadne vode surfaktantom modificiranim uzorcima zeolita. Sintetska otpadna voda pripremljena je s ink jet bojom uz dodatak organskog otapala. Za karakterizaciju surfaktanta na zeolitnoj površini rabljena je FT infracrvena spektroskopija. FTIR spektri upućuju na adsorpciju HDTMA molekula s lancima većinom u gauche konformaciji. Organski kation izmjenjuje se s anorganskim Na+ kationom u unutarnjim i vanjskim površinama zeolita. Posljedica modifikacije je promjena površinskog svojstva zeolita – površina se mijenja iz hidrofilne u hidrofobniju. S 0,5 % (w/w) surfaktantom modificiranih uzoraka zeolita, iz otopine boje s koncentracijom 20 mg/l djelotvornost obezbojenja veća je od 95 %.
Abstract (english)
Adsorption of quaternary ammonium surfactant; hexadecyltrimethylammonium (HDTMA) bromide on a synthetic zeolite mordenite was studied. Clarification of artificial wastewater by the surfactant-modified zeolite samples was examined too. Artificial wastewater was prepared with ink jet dye with addition of organic solvent. To characterize surfactant on zeolite surface FT infrared spectroscopy was used. FTIR spectra indicated adsorption of HDTMA molecules with chains adopting mainly gauche conformation. The organic cation replaced inorganic Na+ cations on the external and internal zeolite surface. This modification resulted in an alteration in the surface property of zeolite – it changed from hydrophilic to more hydrophobic. Untreated zeolite showed little affinity for wastewater clarification. With 0,5 % (w/w) of surfactant-modified zeolite samples, from the solution with dye concentration of 20 mg/l efficiency of clarification is more than 95 %.
