Abstract: [eng] [cze]
Mikroplasty, široko zastúpené vo vodnom prostredí, slúžia ako vektor širokej škály kontaminantov, vrátane ťažkých kovov. Táto práca sa zaoberá adsorpciou piatich ťažkých kovov (Pb, Hg, Zn, Cu and Cd) na polyetylén tereftalát (PET), rozšírený polutant riek a morí. Pokiaľ ide o vplyv veľkosti mikroplastov na proces adsorpcie, nebol zistený jasný trend. Salinita prostredia má značný vplyv na adsorpčný proces s pozorovateľným poklesom adsorbovaných množstiev v prostredí s vysokou iónovou silou. Analyzované ťažké kovy boli zoradené vzostupne podľa ich schopnosti adsorpcie na PET nasledovne: Hg Microplastics are ubiqitous in the aquatic environmet and serve as a vector of wide range of contaminants, including heavy metals. This thesis aimed to examine the adsorption processes of five heavy metals (Pb, Hg, Zn, Cu and Cd) onto polyethylene terephtalate (PET), common river and sea pollutant. There has not been found a clear trend with regard to the influence of the size of the microplastics on the adsorption process. The salinity of the environment, on the other hand, has been found to have a profound impact on the adsorption process, with the observable decline of the adsorbed amounts in the environment with high ionic strength. The analysed heavy metals have been sorted in ascending order by its adsorption on PET as follows: Hg
