The clay used in this study was a natural clay obtained from the Tabuk region in the north of Saudi Arabia. The composites were formulated by mixing 5-10 % mass fractions of clay with PS in the molten state using conventional polymer-processing equipment. Composites of virgin PS and clay were also formulated in order to compare their ability to adsorb heavy metals with that of the recycled composites. The results showed that composites based on recycled PS have a good adsorption capability in comparison with those of the virgin composites. For example, the amount of lead adsorbed per gram of adsorbent was tripled when using composites containing only 5 % of clay and 95% of recycled PS in comparison with those with virgin PS"},{"@xml:lang":"sl","#text":"Iz odpadne potrošniške plastike v obliki jedilnega pribora za enkratno uporabo: krožnikov, skodelic in embalaže za mlečne proizvode, iz polistirena (PS), je bil pripravljen kompozitni material polimer-glina kot adsorbent za odstranitev težkih kovin iz odpadne vode. Glina, uporabljena v tej študiji, je naravna glina, pridobljena iz območja Tabuk na severu Savdske Arabije. Kompoziti so bili izdelani z mešanjem masnih deležev 5-10 % gline s PS v staljenem stanju s konvencionalno opremo za predelavo polimerov. Za primerjavo zmožnosti adsorpcije težkih kovin so bili izdelani kompoziti z deviškim PS in glino ter reciklirani kompoziti. Rezultati so pokazali, da imajo kompoziti na osnovi recikliranega PS večjo vpojno zmogljivost v primerjavi z deviškim kompozitom. Na primer, količina adsorbiranega svinca na gram adsorbenta se je v primerjavi z deviškim PS pri uporabi kompozita s 5 % gline in 95 % recikliranega PS potrojila"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-DP5AREDV","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-DP5AREDV"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-DP5AREDV/308da6a9-14d6-4aaf-8694-641148bd694f/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Inštitut za kovinske materiale in tehnologije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-DP5AREDV/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-DP5AREDV"}}}}
