Carbon nanoparticles modified by graphene for binding heavy metal ions

Popis výsledku v původním jazyce

The designing of new technological methods to effectively remove heavy metals from the environment, is the leading point in a considerable number of research institutions. For the isolation of heavy metals it is possible to use materials capable of adsorbing heavy metals on its surface. The study, presented here, was focused on isolation of heavy metals by nanomaterial approach with subsequent metal detection by electrochemical methods. The aim of our experiment was to isolate cadmium from solution using adsorbents, such as the graphene, expanded carbon and multi-wall carbon nanotubes. We focused on adsorption effects in five different of interaction times - 1; 3; 6; 12 and 24 h - and we compared them with each other. After 1 hour of interaction, it has been established that 99 % of cadmium was adsorbed on the surface of graphene. The MWCNT effect was lower, after 1 hour it was 30 % and after 24 hours it was about 50 %. Expanded carbon has a low efficiency of absorption. Graphene was e
