Özet
Adsorptive removal of some nitroaniline positional isomers was studied by using a humic acid-cryogel based monolithic adsorbent (MLHA). Monolithic material was characterized by FTIR and SEM techniques. The adsorbent was turned into a ligand exchanger form (i.e. Cu-MLHA) by Cu(II) loading. The amount of Cu( II) bound to the monolithic discs was determined by AAS analyses. The effect of contact time and initial nitroaniline concentration on adsorption was studied, and the fit of some isotherm models was analyzed. Maximum observable adsorption capacities recorded on Cu- MLHA were found to be around 150-180mg/g, and the capacities decreased in the order 3-nitroaniline > 4-nitroaniline > 2-nitroaniline.
