“…It was confirmed that in HCl solution with concentration of 0.1 mol/dm 3 , approximately 55% Cu, 60% Ni and 71-72% Co and Zn desorbed from Myriophyllum spitacum [39]. Selenium desorption efficiency from Lemna minor in HCl solution with the same concentration amounted to 18% [48]. Hydrochloric acid (0.5%) was successfully used in multiple desorption of copper from the biomass of Ceratophyllum demersum, Myriophyllum brasiliensis, Eichhornia crassipes, Potamogeton lucens and Salvinia herzogii [15].…”

Abstract:The publication is a synthetic review of many years of research on the possibility of using water plants (macrophytes) to assess pollution of surface waters and the possibility of using the biomass in phytoremediation processes. The results of the research of kinetics and equilibria of heavy metals sorption and desorption conditions were presented in order to repeatedly use the biomass, as well as the research on the influence of abiotic factors on sorption processes. Defence mechanisms of macrophytes, which enable them to vegetate in considerably polluted waters, have been discussed. The results presented herein and carried out in many countries demonstrate that macrophytes can be successfully used in the biomonitoring of water environments and phytoremediation of waters and sewage; however, validation of these procedures requires more detailed research of the mechanisms, which accompany them.

After major pollution by nitrates and pesticides, soils and groundwater in some parts of the world are now facing the emergence of a third major issue of selenium (Se) contamination. Selenium occurrence in ecosystems results naturally from weathering of Se-containing rocks, and is further aggravated by human activities. Selenium is ubiquitous in the environment, and the two main sources of human exposure by Se are food and water. Se, a metalloid, is an important micronutrient due to Se antioxidant, anti-inflammatory and chemo-preventative properties. At normal dietary doses, selenium is an essential diet element that has nutritional proper-E. Lichtfouse (*)

“…The adsorption method is considered the most efficient and economical because of its fast removal rate and minimum pretreatment of samples. [9][10][11][12][13][14][15][16][17][18][19][20] Aluminum, iron, and silica oxides are usually used as adsorbent in the adsorption process to remove heavy metals and metalloids from water. Iron oxides and aluminum oxide have been shown to adsorb Se.…”
