Abstract
U današnje vrijeme, razvijena poljoprivredna proizvodnja predstavlja veliki ekološki problem zbog značajne uporabe pesticida koji ispiranjem iz tla mogu dospjeti u vodne ekosustave. Zbog štetnog djelovanja na žive organizme i ljudsko zdravlje, ostatke pesticida je nužno ukloniti iz voda. Stoga je u ovom radu ispitana mogućnost pročišćavanja vode onečišćene fungicidom karbendazimom (c o =0,992 mg/L) sorpcijom na različitim low-cost sorbensima – prirodnom zeolitu klinoptilolitu, njegovom modificiranom natrijevom obliku, željezovom obliku te sumporom impregniranom obliku, kao i nusproizvodima prerade voća – košticama maslina, trešanja i višanja. Pri danim eksperimentalnim uvjetima, najveći kapacitet (0,064 mg/g) pokazao je natrijev oblik prirodnog zeolita s učinkovitošću uklanjanja od 64,42 %. Međutim, ostatne koncentracije karbendazima bile su u rasponu od 0,353 mg/L do 0,933 mg/L, što je iznad dopuštenih graničnih vrijednosti od 0,5 µg/L za ukupne te 0,1 µg/L za pojedinačne pesticide u vodi za ljudsku potrošnju. Stoga, kako bi se postigla zadovoljavajuća obrada pesticidima onečišćenih voda, buduća istraživanja treba usmjeriti na odgovarajuću modifikaciju postojećih materijala kao i na kombinaciju više metoda obrade, uključujući adsorpciju, napredne oksidacijske procese ili membranske tehnike.
Abstract (english)
Nowadays, developed agricultural production represents a significant ecological problem due to the extensive use of pesticides, which can leach from soil into aquatic ecosystems. Due to their harmful effects on living organisms and human health, it is necessary to remove pesticide residues from water. Therefore, this study examined the treatment of water contaminated with the fungicide carbendazim (c o =0.992 mg/L) through sorption on various low-cost sorbents – natural zeolite clinoptilolite, its modified sodium form, iron form, and sulphur-impregnated form, as well as fruit processing by-products – olive, cherry, and sour cherry pits. Under the given experimental conditions, the sodium form of natural zeolite showed the highest capacity (0.064 mg/g) with a removal efficiency of 64.42%. However, the residual concentrations of carbendazim ranged from 0.353 mg/L to 0.933 mg/L, which is above the permissible limit values of 0.5 µg/L for total and 0.1 µg/L for individual pesticides in water for human consumption. Therefore, in order to achieve a satisfactory treatment of pesticide-contaminated water, future research should be focused on the appropriate modification of existing materials as well as a combination of several treatment methods, including adsorption, advanced oxidation processes or membrane techniques.
