abstract = "The textile industry is one of the largest water-consuming industries in the world. The wastewater generated by the textile industry is a major source of pollution, containing mostly dyes, but also detergents, and heavy metals. Since dyes can have a negative impact on the environment, human and aquatic life, it is really important to find proper solutions for removal of these pollutants from wastewater. In addition, special attention is given to the discovery of new and fast "in situ" methods for identification and quantification of pollutants from wastewater. In this paper, SBA-15, mesoporous silica material, was used as sorbent for removal of Basic Yellow 28 from aqueous solutions. In addition, colored SBA-15 after sorption process was subjected to image analysis, to evaluate if it was possible to quantify sorbed dye on sorbent based on intensity of SBA-15 coloration. The obtained results revealed that SBA-15 could remove 99% of dye within 5 min. The highest efficiency of dye removal was at pH8, using 200 mg of sorbent. According to the Langmuir isotherm model, the theoretical maximum sorption capacity was 909 mg/g. Image-Pro software confirmed that it would be possible to quantify sorbed dye onto SBA-15 with accuracy of 0.98. Overall, SBA-15 demonstrated to be efficient sorbent in removal of Basic Yellow 28 from water, but also to be potential carrier as a sensor for detection of colored pollutants in water., Tekstilna industrija je jedna od najvećih potrošača vode u odnosu na druge industrijske grane. Otpadne vode iz tekstilne industrije su jedan od glavnih izvora zagađenja i uglavnom sadrže boje, ali takođe i deterdžente i teške metale. Pošto boje mogu imati negativan uticaj na životnu sredinu, ljude i vodeni svet, važno je pronaći odgovarajuća rešenja za uklanjanje ovih zagađivača iz otpadnih voda. Pored toga, posebna pažnja je posvećena otkrivanju novih i brzih „in situ” metoda za identifikaciju i kvantifikaciju zagađivača iz otpadnih voda. U ovom radu kao sorbent za uklanjanje Basic Yellow 28 boje iz vodenih rastvora korišćen je SBA-15, mezoporozni silika materijal. Pored toga, obojeni SBA-15 nakon procesa sorpcije podvrgnuti su analizi slike, kako bi se procenilo da li je moguće kvantifikovati sorbovanu boju na sorbentu na osnovu intenziteta obojenosti SBA-15. Dobijeni rezultati su pokazali da SBA-15 može ukloniti 99% boje u roku od 5 minuta. Najveća efikasnost uklanjanja boje bila je pri pH 8, korišćenjem 200 mg sorbenta. Prema Langmuirovom modelu, teoretski maksimalni kapacitet sorpcije bio je 909 mg/g. Softver Image-Pro je potvrdio da je moguće kvantifikovati boju na SBA-15 sa tačnošću od 0,98. SBA-15 se pokazao kao efikasan sorbent u uklanjanju Basic Yellow 28 boje iz vode, ali i kao potencijalni senzor za detekciju obojenih zagađivača u vodi.",
