Abstract:Možnosti ravnanja z odpadnimi goščami iz komunalnih čistilnih naprav, zaradi povišane vsebnosti težkih kovin, omejuje zakonodaja. Kljub visokemu deležu organskih snovi in hranil, je njihova uporaba v kmetijstvu prepovedana. Ena izmed obetajočih naprednih metod odstranjevanja težkih kovin je adsorpcija na magnetne nanodelce, ki se jih po čiščenju odstrani z magnetno separacijo. Pri magistrskem delu smo sintetizirali in okarakterizirali tri sisteme magnetnih nanokompozitov: maghemit – L-lizin, ki so se razlikovali po načinu vezave L-lizina. Za uspešno se je izkazala le kovalentna vezava. Ta sistem je pri čiščenju vzorca mulja dosegel 37 % učinkovitost odstranitve Zn, 27 % Cr(VI) in 26 % Cu.

Title:Coating of Magnetic Nanoparticles with Lysine: Effect of Bonding on the Efficiency of Metal Removal from Sludge
Abstract:Due to increased content of heavy metals, possibilities of waste sludge management from municipal wastewater treatment plants are limited by legislation. Despite of high content in organic substances and nutrients, sludge use in agriculture is restricted. One of the advanced methods for metal removal is adsorption on magnetic nanoparticles, which can later be removed by magnetic separation. Three systems of magnetic nanocomposites: maghemite – L-lysine, which differed in the L-lysine binding method, were synthesized and characterized. Only chemical bonding was successful. This system achieved 37, 27 and 26 % removal efficiency of Zn, Cr(VI), and Cu from a sludge sample respectively.
Keywords:sludge, heavy metals, magnetic nanoparticles, maghemite, L-lysine
