The obtained results showed that the steel-making slag is an effective adsorbent for the removal of Cr(VI) ions from aqueous solutions. The adsorption of Cr(VI) with the steel-making slag follows the Langmuir isotherm equation. Among the tested kinetics models in this study (pseudo-first-order, pseudo-second-order, Elovich and intraparticle-diffusion models), the pseudo-second-order equation successfully predicted the adsorption. The thermodynamic parameters for the adsorption process were determined and discussed</dc:description><dc:description xml:lang="sl">V članku je predstavljena raziskava odstranjevanja ionov Cr(VI) iz vodne raztopine z jeklarsko žlindro kot poceni adsorbenta pri različnih eksperimentalnih razmerah. Dobljeni rezultati so pokazali, da je jeklarska žlindra učinkovit adsorbent za odstranjevanje Cr(VI) ionov iz vodnih raztopin. Adsorpcija ionov Cr(VI) z jeklarsko žlindro se sklada z Langmuirovo izotermno enačbo. V tej študiji je od preizkušenih kinetičnih modelov (psevdo prvega reda, psevdo drugega reda, Elovichev model in model difuzije med delci) enačba psevdo drugega reda uspešno napovedala adsorpcijo. Določeni in obravnavani so termodinamični parametri za proces adsorpcije</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-IGWRKHA0"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-IGWRKHA0" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-IGWRKHA0/11611eb7-a227-4fd4-aec1-1e6172912709/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Inštitut za kovinske materiale in tehnologije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-IGWRKHA0/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-IGWRKHA0" /></ore:Aggregation></rdf:RDF>
