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。
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。
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
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。
