Secondary title: Adsorption capacity of various adsorbents for decolorization of wastewater
Secondary abstract: Adsorption is applied for the removal of dyes from wastewater effluent from textile and other industries. Dyes from wastewater need to be removed before it mixes with water bodies. Among the treatment options, adsorption appears to have considerable potential for the removal of colour from wastewaters. Activated carbon is the most widely used adsorbent, but its use is limited due to its high cost. This cost problem has led to a search for the use of alternate cheap and efficient materials. The purpose of this thesis was to test the possibility of using different materials for adsorption of textile dye. Four different materials were used; waste ashes by burning coal, sawdust, sludge and activated carbon. Adsorption was influenced by various parameters such as initial dye concentration, dose of adsorbent and contact time.

Abstract (ePrints): Adsorpcija barve na trdnem adsorbentu in s tem tudi proces razbarvanja, se običajno vežeta na procese čiščenja odpadnih vod, v glavnem tekstilne ali kakšne druge industrije. Preostala barva v odpadni vodi je pomemben faktor pred izpustom le-te v vodne tokove. Med številnimi tehnikami za odstranjevanje barv, postopek adsorpcije daje dobre rezultate. Kot sorbent za odstranjevanje barv iz odpadnih vod se največ uporablja aktivno oglje, zaradi odlične adsorpcijske sposobnosti, vendar je njegova razširjena uporaba omejena zaradi visoke cene. Zaradi tega se raziskave na področju čiščenja odpadnih vod tekstilne in drugih industrij nagibajo k uporabi naravnih materialov, predvsem zaradi njihove učinkovitosti in nizke cene. Cilj tega diplomskega dela je predstaviti možnost uporabe različnih adsorbentov pri procesu adsorpcije barve iz tekstilne industrije, s čimer se lahko pride do dragocenih podatkov vezanih na možnost širše uporabe pri čiščenju odpadnih obarvanih vod. Pri procesu adsorpcije sem uporabila štiri adsorbentske materiale, in sicer odpadni pepel iz Termoelektrarne-toplarne Ljubljana, žagovino, odpadno blato iz centralne čistilne naprave v Ljubljani in prašnato aktivno oglje proizvajalca Merck. Zanimalo nas je kako začetna koncentracija vodne raztopine, količina dodanega adsorbenta in kontaktni čas vplivajo na sam proces adsorpcije.
