ferrous hydroxide

Everyone in the know in the discussion of the color of ferrous hydroxide , I found in teaching : purity of ferrous oxide is white .

在知道中大家都在讨论氢氧化亚铁的颜色问题，我在教学中发现：纯氢氧化亚铁是白色的。

On the mechanism of hydrogen evolution from aqueous suspension of ferrous hydroxide

Fe（OH）2水悬浮液放氢机理的研究

Maghemite is directly prepared by pyrolysis of ferrous hydroxide as precursors in the presence of CO2-3 with microwave irradiation .

用硫酸亚铁为原料加NH3·H2O得到的Fe（OH）2作前驱物，在有CO32-存在下进行微波快速热解可直接得到γ-Fe2O3。

Synthetic method of crystal seed of iron oxide black and influences of oxidized time , amount of ferrous sulfate and sodium hydroxide , reaction , temperature etc were studied experimentally . Better reaction conditions were determined .

通过实验研究了氧化铁黑晶种的合成方法以及氧化时间、硫酸亚铁用量、氢氧化钠用量和反应温度等因素对晶种合成的影响，并且确定了较好的合成条件。

Therefore , a number of methods have been developed for removing gossypol from cottonseed meal including solvent extraction of free gossypol ( FG ), chemical treatment with ferrous sulfate or calcium hydroxide , and microbes fermentation .

为此，人们研究了许多脱毒方法，如有机溶剂浸提、硫酸亚铁处理、氢氧化钙处理以及微生物发酵等方法。
