Abstract
Gadolinij pripada elementima rijetkih zemalja te je tehnološki važan element. Široka upotreba gadolinija prouzročila je problem nakupljanja gadolinija u okolišu i njegov utjecaj na živi svijet. Nanočestice željeza posjeduju sposobnost akumuliranja zagađivača iz okoliša, koja je poboljšana primjenom ugljikovih nanocjevčica kao nosača za nanočestice željeza. Priređeni su nanokompoziti ugljika i željeza te su karakterizirani pomoću pretražne elektronske mikroskopije i mjerenjem magnetsne susceptibilnosti. Spektrometrijom mase uz induktivno spregnutu plazmu ispitana je adsorpcija kelatno vezanog i ionskog gadolinija na nanočestice kompozita te je provedena varijacija mase nanokompozita kod adsorpcije gadolinija. Utvrđeno je da čestice nanokompozita vrlo dobro adsorbiraju gadolinij pri uskom području niskih koncentracija, a povećanjem koncentracije gadolinija sposobnost adsorpcije čestica značajno opada.
Abstract (english)
Gadolinium belongs to the rare earth elements (REEs) and is a technologically important element. The widespread use of gadolinium has caused the problem of gadolinium accumulation in the environment and its impact on the living world. Iron nanoparticles can accumulate pollutants from the environment, which is improved by using carbon nanotubes as a carrier for iron nanoparticles. Carbon and iron nanocomposites were prepared and characterized using scanning electron microscopy and magnetic susceptibility measurements. The adsorption of chelated and ionic gadolinium on composite nanoparticles was tested by mass spectrometry with inductively coupled plasma, and the mass variation of the nanocomposite during gadolinium adsorption was performed. It was found that nanocomposite particles adsorb gadolinium very well in a narrow range of low concentrations, and with an increase in gadolinium concentration, the adsorption capacity of the particles decreases significantly.
