Dehalogenation process of organic halogenated matters in contaminated water with nano-iron during its formation as alternative for static permeable barriers

摘要

dehalogenace organic halogenated substances in contaminated waters of nano iron at its inception is thatin water contaminated with organic halogenated substances are gradually pridu00e1vu00e1 first aqueous solution of ferrous and / or iron sol which contains chemically bound water.along with in the water dissolving salts or complex salts and palladium stru00edbra and neionogennu00edm tenzidem, while the concentration of u017eeleznatu00fdch and / or ferric salts are in the range of 0.01 g / l to 5 g / l and a second aqueous solution containing 20 g / l to 0.5 g / l ag and / or pd in the form their soluble salts and an aqueous solution of alkali metal borohydridu, vu00fdhodne borohydridu sodiumwhen the concentration of borohydridu ranged from 0.005 g / l to 1 g / l, while the second solution contains at the same time, 0.1 g / l to 5 g / l mravencanu nitrate.
