Abstract :
Compounds of mercury, chrome and arsenic are very dangerous to man due to their instability and their interaction with fats, providing long periods of partial ejection, i. e. the time during which half of the agent assimilated with the organism ejects or destructs. Hence, the control of mercury, chrome and arsenic content in the water is very critical. In this paper, the sorption capabilities of the nano-powders of aluminum oxide and aluminum hydroxide of the class "HCh" annealed at the temperature 450 degC with respect to Hg (II), As (III), Cr (VI) for water purification are examined.
