| 520 | |a This study investigated the utilisation of Luffa cylindrica activated carbon as a low-cost adsorbent in the removal of vanadium(V) from textile industry effluent in a batch adsorption experiment. The adsorption rate was studied for contact time, pH, and adsorbent dosage. The effect of pH on vanadium(V) removal was studied with 0.2 g/100 ml adsorbent dose, 10 min contact time, and textile effluent solution. The maximum removal efficiency was 99.90 % at pH 4, 97.43 % at 60 min of contact time, and 97.83 % at an adsorbent dosage of 1.0 g. The characterisation results from FTIR and SEM indicated that the adsorbents" potential was fully exploited. In this study, the experimental findings were fitted using Langmuir and Freundlich isotherm models. Freundlich model gave a better fit of the experimental data. The kinetic data by the pseudo-second order kinetic model gave a better fit than the pseudo-first order kinetic model. | ||
| 520 | |a U ovom radu istražena je primjena aktivnog ugljena Luffa cylindrica kao jeftinog adsorbenta za uklanjanje vanadija(V) iz otpadnih voda tekstilne industrije u eksperimentu šaržne adsorpcije. Stupanj adsorpcije proučavan je za vrijeme kontakta, pH i dozu adsorbenta. Učinak pH na uklanjanje vanadija(V) proučavan je s dozom adsorbenta od 0,2 g/100 ml, vremenom kontakta od 10 min i otopinom tekstilnih otpadnih voda. Maksimalna učinkovitost uklanjanja bila je 99,90 % pri pH = 4, 97,43 % pri vremenu kontakta od 60 min i 97,83 % pri dozi adsorbenta od 1,0 g. Rezultati karakterizacije FTIR-a i SEM-a pokazali su da je potencijal adsorbenata u potpunosti iskorišten. U ovom su istraživanju eksperimentalni nalazi prilagođeni Langmuirovim i Freundlichovim modelima izoterme. Freundlichov model dao je bolju prilagodbu eksperimentalnim podatcima. Kinetički podatci kinetičkog modela pseudo-drugog reda dali su bolji rezultat od kinetičkog modela pseudo-prvog reda. | ||
