Sorpcija lindana iz vode pomoću makroporoznog kopolimera na bazi glicidil metakrilata

Abstract

Organohlorni pesticid - lindan, smatra se potencijalno kancerogenim jedinjenjem. Lindan i njegovi ostaci mogu da opstanu u životnoj sredini veoma dugo, migrirajući i potencijalno izazivajući zagađenje životne sredine. Ostaci lindana mogu dospeti i u ljudski organizam kroz lanac ishrane, jer je ovo potencijalno toksično jedinjenje sklono bioakumulaciji. Kontaminacija lindanom je globalni problem, a njegovo uklanjanje iz životne sredine je neophodno. U ovom istraživanju sorpcija lindana iz vodenog rastvora urađena je sa makroporoznim kopolimerom na bazi glicidil metakrilata, koji se pokazao kao veoma efikasan sorbent, sa sorpcijom lindana od oko 0%. Za određivanje koncentracije lindana korišćena je analitička tehnika, gasna hromatografija sa detektorom za hvatanje elektrona GC-ECD. Osim sorpcije, uspešno je urađena i desorpcija lindana.

Organochlorine pesticide - lindane, is considered as potentially carcinogenic compound. Lindane and its residues can persist in the environment for a very long period, migrating and potentially causing environmental pollution. Residues of lindane can also enter the human body through the food chain, because this potentially toxic compound is prone to bioaccumulation. Lindane contamination is a global problem, and its removal from the environment is essential. In this research, the sorption of lindane from an aqueous solution was performed with a macroporous copolymer based on glycidyl methacrylate, which proved to be a very effective sorbent, with lindane sorption of about 80%. An analytical technique, gas chromatography with an electron capture detector GC-ECD, was used to determine the concentration of lindane. In addition to sorption, desorption of lindane was also successfully performed.
