Abstract Phytoremediation tests on heavy metals bioaccumulation were performed during 2012-2014 with aquatic species Lemna minor, Pistia stratiotes, Eichhornia crassipes, Vallisneria spiralis, Hydrilla verticillata, Cladophora glomerata on samples of contaminated waters collected from the toxic pond of waste landfill Şomârd-Mediaş, Sibiu County. With the purpose to check the species capacity for heavy metal removal and bioaccumulation, comparative analysis of water samples wa...

With the aim of contribute to a bioremediation technology drafting, this paper presents a preliminary research on bioremediation of wastewaters polluted with heavy metals and other toxic contaminants. Bioremediation tests were performed with aquatic species Lemna minor, Vallisneria spiralis, Eichhornia crassipes, Hydrilla verticillata, Pistia stratiotes, Cladophora glomerata, on samples of contaminated waters resulting from the toxic pond of waste landfill Şomârd-Mediaş, Sibiu Co...

The macrophyte Pistia stratiote was used as biosorbent for the removal of Black Krom KJR (BK-KJR) dye in synthetic aqueous solution. Initially, some tests were performed to verify the best operational conditions such as pH, biosorbent particle size, sorption temperature and stirring speed, which were later used in the kinetic and equilibrium tests. All tests were performed in duplicate. The highest removal rates of the pollutant were achieved at the process conditions of initial pH 2, granulo...
