摘要

汞、铬和砷的化合物对人体非常危险，因为它们的不稳定性和与脂肪的相互作用，提供长时间的部分喷射，即与生物体同化的一半物质喷射或破坏的时间。因此，控制水中汞、铬和砷的含量是非常关键的。本文研究了经450℃退火的HCh类氧化铝和氢氧化铝纳米粉末对Hg (II)、As (III)、Cr (VI)的水净化吸附性能。

Absorption of the Cr(VI), Hg(II), As (III) ions with the Al/sub 2/O/sub 3/ nano-powder from the water

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.
