Abstract
Adsorpcija kao učinkovita metoda za uklanjanje bojila iz otpadnih voda, kao i primjena lignoceluloznih materijala kao adsorbensa, predmet su brojnih istraživanja. U ovome radu istražena je mogućnost primjene pivskog tropa, otpadnog lignoceluloznog materijala iz proizvodnje piva, kao adsorbensa za uklanjanje sintetskih bojila metilenskog modrila i kongo crvenila iz modelnih vodenih otopina u koloni s nepokretnim slojem adsorbensa. Kontinuirani adsorpcijski eksperimenti provedeni su s ciljem ispitivanja učinkovitosti uklanjanja bojila u ovisnosti o promjeru kolone (13 i 18 mm), visini sloja adsorbensa (2 i 4 cm), veličini čestica adsorbensa te početnoj koncentraciji bojila (10, 50 i 100 mg/L). Dobiveni rezultati pokazali su kako se pivski trop može koristiti za učinkovito uklanjanje metilenskog modrila i kongo crvenila iz vodenih otopina u koloni s nepokretnim slojem adsorbensa, ali je za svako bojilo potrebno optimirati parametre provođenja procesa (promjer kolone, visina sloja adsorbensa, veličina čestica adsorbensa) kako bi se postigao visoki postotak uklanjanja bojila uz istovremenu mogućnost dužeg korištenja kolone (propuštanja većega volumena modelne otopine kroz kolonu prije zasićenja kolone).
Abstract (english)
Adsorption as an efficient method used dye removal, as well as utilization of lignocellulosic material for the role of adsorbent, are represented as a course of numerous studies. In this study the possibility of brewer’s spent grain, the lignocellulosic waste material form beer industry, is explored as adsorbent for the synthetic dyes Methylene blue and Congo red’s removal from simulant aqueous solutions in a fixed-bed column. Continuous adsorption experiments were carried out with the aim to test the efficiency of dye removal in dependency of column diameter (13 and 18 mm), bed height (2 and 4 cm), particle size of adsorbent and different inlet dye concentration (10, 50 and 100 mg/L). The obtained results showed how brewer’s spent grain can be used for effective Methylene blue and Congo red removal from aqueous solutions in fixed-bed column, however for every dye there is a necessity to optimize parameters of process conduction (column diameter, bed height, particle size of adsorbent) in order to achieve dye removal’s high percentage and to simultaneously enable longer column usage (the leakage of stimulant solution through column in larger volume before column saturation).
