It is pointed out that under the condition of the temperature of 1120℃, the reaction time of 16 mm and the carbon content of 27%, the metal transformation rate of sponge iron used for general metallurgy is up to 90%. But the optimal carbon content is 29% for iron sponge to treat DSD acid oxidation wastewater. Under condition of the wastewater's pH value of 3 to 5 and the reaction time of 40min, the removal rates of COD and color are 68% and 90%, respectively. The BOD/COD ratio is up to 0.425 when DSD oxidation acid water is treated with sponge iron.

A highly sensitive fluorescence quenching method for the determination of iron based on the system of iron-oxfloxacin-SDS has been developed. In NaAc-HAc medium, iron reacts with oxfloxacin and SDS to form a non-fluorescent ternary complex which can quench the fluorescence intensity of oxfloxacin.

在表面活性剂十二烷基硫酸钠存在下，铁能与氧氟沙星形成络合物而猝灭氧氟沙星分子的内源性荧光，使其荧光强度显著降低，据此，提出了铁氧氟沙星SDS体系测定铁的荧光分析新方法。

The optimum HCI/ferrous chloride molar ratio was 1/3.3 when ironic chloride was generated by using hydrogen peroxide. The generated ironic chloride oxidized acetoin in good yield and could be recycled for many times.

用双氧水再生氯化铁时，加入浓盐酸最佳用量与氯化亚铁的摩尔比为1：3.3，再生后的氯化铁氧化效果良好，可多次循环使用。

The obtained results show: After applying Yelükang ball fertilizer, the active iron and total iron in the chlorotic peach tree leaves increased by 18.7%~19.5%, the chlorotic degree of peach trees decreased 2~3 scales, the fresh weight and dry weight of 100 leaves also increased apparently; the yield per tree increased by 56%~89%.

结果表明：施用球肥可使桃树叶片失绿程度降低2～3级，百叶重明显增加，单株产量提高56%～89%，全铁和活性铁含量提高18.7%～19.5%，可降低叶片中N，P，K，Cu和Zn的含量，使这些营养元素与铁的拮抗作用减弱。

The fast and slow rates of the reduction electrons on the surface of iron core in liver ferritin of Dasyatis akajei were studied by direct electrochemical technology which was also used to study the kinetic order and law of iron release.

On the other hand, Cu, Co and Ni are all present in manganese phase in the hydrogenic nodules.

这些过渡金属元素在成岩作用形成的结核中的存在与铁锰结核中锰矿物和铁的氧化物、氢氧化物的晶体化学特征密切相关，而在水成作用形成的铁锰结核中的富集与锰矿物和铁的氧化物、氢氧化物的晶体化学特征关系不大。

In 75m in the South China Sea, Fe enriched from a large range of concentrations stimulated the growth of nanoplankton. For the picoplankton, Fe enrichment of nano-molar level increased the cell abundance of Euk, on the other hnad, Syn and Pro had significant responses to higher concentration of Fe enrichment.

75米层海水铁添加实验表明，不同浓度的铁均促进nano-级的浮游植物的生长；对于超微型浮游植物来说，纳摩尔级铁的添加有利于超微型真核生物的生长，而更高浓度的铁添加则对聚球藻和原绿球藻的生长有利。

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