The possibilities of redox reactions between chromate (Cr(Ⅵ)) and ferrous iron (Fe(Ⅱ)) in alkaline system were investigated in the laboratory and analyzed from point view of thermodynamics with a purpose to control chromium leaching from incineration fly ashes.

为了控制焚烧飞灰中铬的浸出,将FeSO4加入焚烧飞灰水系统中和Cr(Ⅵ)的碱性水溶液中,试验二价铁(Fe(Ⅱ))对Cr(Ⅵ)的还原效果,并检验了Cr(Ⅵ)的还原产物的稳定性。

In this paper,palladium(Ⅱ)-catalyzed allylic rearrangement reaction was described.

近年来二价钯催化反应已成为研究热点,其催化的烯丙位重排反应则研究较少。

In this paper,Palladium(Ⅱ)－catalyzed allylic rearrangement reaction is described.

近来,二价钯催化反应以其高选择性、环境友好以及原子经济性等诸多优点成为研究热点。
