dcterms:description
During the experimental testing of antimony elimination from mine water collected at the Sb deposit Poproč (Slovakia) three remediation techniques were used: absorption on activated carbon; ion exchange resin technique (use of single strongly acidic cation-exchanger - catex Amberlite IR 120 and use of combination of strongly acidic catex and weakly basic anion-exchanger - annex Purolite A-100) and absorption on commercial sorbent GEH (granulated Fe(OH)3 with content of βFeOOH and H2O). Characteristic for the tested mine water was the pH value 7.3 and content 120 µg.l-1 of Sb that is 24 times higher concentration than the limit of Sb content in drinking water (5 µg.l-1) ordered by Decree no. 252/2004 Coll. (CZ) and the SR Government Regulation No. 354/2006 Coll. (SK). The results of the column experiments confirmed low ability (20 %) of activated carbon in the process of Sb elimination. Furthermore, use of single strongly acidic catex reflected relatively low (41 %) efficiency in elimination of Sb from tested mine water. On the other hand, combination of strongly acidic catex and weakly basic annex has confirmed the assumed high efficiency of Sb elimination (98 %). Use of sorbent GEH also resulted in high ability of Sb elimination from mine water (98 %). The pH values of tested water were not significantly changed after using all of the remediation techniques. Ion exchange resins (combination of catex and annex) and absorption on sorbent GEH have proved very good ability in the case of elimination of Sb from mine water.
