Chromium is widely used in the form of metal and in the form of compounds. The compounds of Cr(VI) are highly toxic. Therefore, the wastewater containing chromium must be thoroughly cleaned by sorption, extraction, electrochemical and biochemicals methods. Methods based on the reduction of Cr(VI) occupy an important place. A large number of reducing agents, including FeSO4, has been proposed for this. Studies carried out earlier showed that during this reaction a magnetoactive compound is formed. Lignosulfonic aci...

Screening the local flora for metal bioaccumulators is of great importance, the aim being that of finding species valuable for bioremediation (bioindicators, phytostabilizers, phytoextractors) or biomining. Chromium content was determined, through atomic absorption spectrometry (HR-CSAAS, air-acetylene, 357 nm) in aboveground organs eight common species growing on the beaches and adjacent areas in Constanta, Romania: Argusia sibirica, Atriplex sagittata, Echium italicum, Conium maculatum, Malva sylvestris, Onopord...
