20.500.12556/DKUM-21084 ODSTRANJEVANJE IZBRANIH ONESNAŽIL IZ VODE Z ZEOLITOM IN KELATNIM POLIMEROM THE REMOVAL OF SELECTED CONTAMINANTS FROM WATER USING ZEOLITE AND CHELATE POLYMER MATERIAL Z razgradnjo rastlinskega materiala, živali in mikroorganizmov v tleh in vodi se proizvajajo različne kompleksne organske molekule, ki jih imenujemo naravne organske snovi (NOM). Namen naloge je bil uspešno odstranit naravne organske snovi iz modelne vode. Ker moramo omenjene snovi iz vode odstraniti, se v zadnjem času v ta namen veliko uporabljajo membrane. Zato smo v nalogi izvajali poskuse s tistimi snovmi, ki lahko najbolj mašijo membrane. Izbrali smo predstavnika sladkorjev, polietilenglikol in alginat. Delo je potekalo z njihovo adsorpcijo na zeolit 4A in 13X, proizvajalca Silkem Kidričevo in Petro Chemicals Limited iz Indije ter s kelatnim polimerom P 26T, proizvajalca Biomontan. Z zeolitom 4A in 13X ter kelatnim polimerom P 26T se organske snovi zelo slabo odstranijo iz raztopine glukoze in glutaminske kisline. Smo pa z njimi bolj uspešno odstranili alginat iz raztopine. Poliglikol iz raztopine odstranita zeolita 4A in 13X. Glede na raziskavo predlagamo za odstranitev poliglikola iz raztopine zeolit 4A, ki ga odstrani do 76,4 %, za alginat pa Petrosorb 26T, ki ga odstrani do 94,4 %. Decomposition of plant material, animals and micro-organisms in soil and water produce a variety of complex organic molecules, called natural organic matter (NOM). Membrane filtration are becoming attractive water treatment methods, but can be fouled by certain pollutants. The purpose of the thesis was to successfully remove those natural organic matter, which foule the membrane the most. Therefore, three substances were choosen: sacharide, polyglycol and alginate. Experiments were carried out by adsorption on zeolite 4A and 13X, purchased from manufacturer Silkem Kidričevo and Petro Chemicals Limited in India as well as a chelate polymer P 26T, purchased from Biomontan. Organic matter in a solution of glucose and glutamic acid is hard to remove by using zeolites 4A and 13X and chelate polymer P 26T. We ware more successful removing alginat from solution by using those zeolites and chelate polymer. Polyglycol was removed from solution using zeolite 4A and 13X. According to the survey, the removal of Polyglycol using zeolite 4A, which removes up to 76,4% and for alginate removal petrosorb 26T, which removes up to 94,4% are suggested. odpadna voda zeolit kelatni polimer P 26T adsorpcija naravne organske snovi waste water zeolite chelate polymer P 26T adsorption natural organic matter true true false [T.
