“…Anions with a low lyotropic number, high hydration, or strong water-structure-making tendency decrease the CP. For example, SO 4 2− is two times more effective than Cl − [28,56-60]. Therefore, it is possible to adjust the cloud point to room temperature (22 • C) by a simple control of surfactant and Na 2 SO 4 concentrations (at 3 wt.% with TX-114 and 6 wt.% using Lutensol AO7), and reduce the heating energy cost of the large scale cloud point extraction.…”

“…In another such study, "lais team demonstrated that it is possible to atain removal eiciencies of 4 3% for Cu and from 43 to 63% for Zn, whereas a removal yield of 2% was measured for total P"Hs [40,41]. The results were improved replacing cocamidopropyl betaine with cocamidopropyl hydroxysultaine (up to 0% P"Hs and Pb removal, in three diferent polluted soil types) [42]. "y carefully choosing the acidic species (hydrochloric, nitric, sulphuric and lactic acids and ethanol) for leaching metals from soil in combination with non-ionic, ionic and amphoteric surfactants, "lais and co-worker studied the simultaneous removal of heavy metals and pentachlorophenol by lotation [43].…”

“…Among these contaminants lead (Pb) and decabromodiphenyl ether (BDE209) are most widespread [7,8]. These two contaminants could persist in the environment for long periods and adversely affect the health of organisms [9,10]. Soils from EWRSs are often subjected to organicinorganic mixed contamination caused by the extensive and primitive disposal or recycling of e-waste [10].…”
