铁酸盐

Ferric arsenate is also not stable in alkaline cement cast admixes.

含铁砷酸盐在碱性水泥投入混合时也不稳定。

Ferric arsenite sulfate is also of recent interest and may prove to be useful in stabilizing arsenic.

含铁的亚砷酸盐和硫酸盐也是新近的关注点并且可以证明对使砷稳定有用。

There are other metal arsenates, such as those of Fe,Zn,Cu, and Pb, which are less soluble and more stable in the neutral pH region than calcium arsenates or ferric arsenate, but these have not been seriously considered as disposal forms.

还有其他金属砷酸盐，例如那些 Fe、 Zn、 Cu和 Pb，比起砷酸钙或者砷酸铁来，这些物质在中性的 pH 值范围内很少是可溶并且更稳定的，但是这些物质没被以处理的形式认真慎重地考虑过。

A method for the determination of potassium ferrate based on the oxidation of chromite was introduced in this paper.

以亚铬酸盐氧化还原反应为基础建立了高铁酸钾的滴定分析方法。

Salt of ferricyanic acid obtained by oxidation of a ferrocynide.

由于氰化铁氧化而形成的氰铁酸的盐。

Salt of ferrocyanic acid usually obtained by a reaction of a cyanide with iron ''.

氰亚铁酸形成的盐，通常由氰化物和硫酸铁反应形成。

Salt of ferrocyanic acid usually obtained by a reaction of a cyanide with iron sulphate.

氰亚铁酸形成的盐，通常由氰化物和硫酸铁反应形成。

A salt of hydrocyanic acid; cyanide.

由于氰化铁氧化而形成的氰铁酸的盐。

It is found that the initial pH,ρ(H_2O_2) and ρFe~(3+ of the solution have significant effects in this photooxidative process. The removal percentage of COD_ is higher under solar irradiation than under UV irradiation. Under the selected conditions, using solar/H_2O_2/ferric oxalate complexes to treat the landfill leach has good efficiency. landfill leach ; ferric oxalate ; photocatalysis

已有的研究表明，Fe3+羧酸盐络合物具有光催化降解有机物的性能[1-3]；当草酸铁络合物体系中存在一定量的H2O2时，在太阳光或紫外光照射下，可发生类Fenton反应产生羟基自由基[4]，而草酸铁络合物可在一定程度上循环利用，使Fe3+和C2O2-4可以重新形成草酸铁络合物：2[Fe(C2O4)n](3-2n)hν2Fe2++(2n-1)C2O42-+2CO2(1)Fe2++H2O2

Acid usually obtained by a reaction of a cyanide with iron sulphate.

氰亚铁酸形成的盐，通常由氰化物和硫酸铁反应形成。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
