Abstract

U ovom radu praćeno je uklanjanje arsena adsorpcijom na Fe(OH)3 i na adsorpcijske mase Bayoxide i Titansorb. Pokusima su određene konstante Freundlichove i Langmuirove izoterme za vodovodnu i destiliranu vodu. Najbolju učinkovitost vezanja arsena imao je Fe(OH)3, a najlošiju adsorpcijska masa Titansorb, a sve tri adsorpcijske mase bolje su uklanjale arsen iz destilirane vode nego iz vodovodne vode. Uklanjanjem arsena propuštanjem otopine kroz kolone s masama Bayoxide i Titansorb postignuto je potpuno uklanjanje arsena iz vode, a zasićenje kolona do pojave arsena u izlaznoj vodi u koncentraciji od 10 μg/L primijeceno je za masu Bayoxide kod volumena mase 1234, a kod mase Titansorb kod volumena mase od 949, po čemu zaključujemo da masa Bayoxide bolje uklanja arsen od mase Titansorb.

Abstract (english)

In this work it is monitored arsenic removal by adsorption on Fe(OH)3 and adsorption masses Bayoxide and Titansorb. In experiments were determined constants of Freundlich and Langmuir isotherms for tap water and distilled water. The best efficiency of binding arsenic has had Fe(OH)3, and the worst adsorption mass was Titansorb. All three adsorption masses have had better removal of arsenic in destilled water than in tap water. Arsenic removal by passing the solution through a column with the masses Bayoxide and Titansorb achieved the complete removal of arsenic from water, and saturation of column until the arsenic appeared in water output in concentration of 10 mg/L was noted for adsorption mass of Bayoxide on 1234 volume of mass, and for the adsorption mass of Titansorb on 949 volume of mass, by which we conclude that adsorption mass of Bayoxide better removes arsenic than adsorption mass of Titansorb.
