Under the same condition,the maxi-um 〓 adsorption for goethite was 3,3.5,and 8 times as kaolinite,bayeriteand gibbsite respectively,and also the maxium 〓 adsorption of YB colloid was1.4,3,and 7 times as that of 〓 LR colloids respectively.

同样条件下针铁矿对〓的最大吸附量分别相当于高岭石、三羟铝石、三水铝石的3，3.5，8倍；黄棕壤胶体对〓的最大吸附量相当于红壤胶体〓的1.4倍，红壤胶体〓的3倍，砖红壤的7倍。

In the soil, water, modern sediments, hematite, needles is the main iron ore minerals.

In DS 4J, the negative relationship of Ti and Fe is observed, and Mn, Si, Al and Ca elements are often found in the magnetic minerals, and a lot of goethite and limonite minerals, as well as magnetic mineral corrosion and some neogenic magnetic minerals are also found.

DS-4J样的磁性矿物中Fe与Ti元素呈明显的负线性相关关系，Si、Al、Ca的含量较高，矿物以磁铁矿、赤铁矿、针铁矿和褐铁矿为主，并明显见有磁性矿物被溶蚀和新生的磁铁矿。

It is mainly in submicro particles adsorbed at the crystal rims of clay mineral kaolinite and illite,or in micro particles included within limonite,little amount of gold is in the adsorbed phase of limonite.

研究表明，这些金以超显微金的形式存在于粘土矿物高岭石、水云母的晶体边缘，或混杂于褐铁矿中的针铁矿晶体集合体之间，少数呈褐铁矿的吸附相形式存在。

Kinetics of methyl parathion or carbaryl adsorption could be described by First-order equation, Elovich equation and Two-constant equation.

结果表明，Langmuir方程能较好的描述甲基对硫磷和西维因在3种矿物表面的等温吸附过程，且蒙脱石对农药的最大吸附量大于高岭石和针铁矿。

Result showed that DFOB could promote the release of REEs from goethite but increase the adsorption onto humic acid and montmorilonite. The increase in adsorption amount is attributed to the release of iron from these two minerals.

结果表明，DFOB能促进稀土元素从针铁矿表面的释放，但却提高了腐殖酸和蒙脱土对稀土的吸附，这种吸附量的增加是由于DFOB促进矿物中铁的释放而增加了矿物中吸附点位所造成的。

The precipitation obtained is roasted and redissolved.

后序工艺中利用针铁矿除铁，除铁率大于98.5%。

The effect of the concentration, pH of several ligands such as acetate, oxalate, tartrate and phosphate solution and their orders added on the adsorption and activity of BSA and acid phosphatase on yellow brown soil, latosol, kaolinite, goethite and -MnO2 was first systematically studied by using batch and FTIR methods after analyzed and studied the relative literature that reported in the world.

论文在分析总结了国内外有关研究的基础上，用批量法和傅立叶变换红外光谱法首次系统地研究了乙酸、草酸、酒石酸和磷酸几种配体的浓度、pH及加入顺序对牛血清白蛋白、酸性磷酸酶在黄棕壤、砖红壤、高岭石、针铁矿和二氧化锰表面的吸附行为及活性的影响，探讨了这些配体对蛋白吸附机理及二级结构的影响。

The effect of the concentration, pH of several ligands such as acetate, oxalate, tartrate and phosphate solution and their orders added on the adsorption and activity of BSA and acid phosphatase on yellow brown soil, latosol, kaolinite, goethite and δ-MnO〓 was first systematically studied by using batch and FTIR methods after analyzed and studied the relative literature that reported in the world. The impact of these ligands on the adsorption mechanism and secondary structure of protein was simultaneously engaged.

The experiment result shows that if Iron in the pickle of copper-smelting smoke ash is removed by Oxygen or oxidation combined with Hydrogen peroxide, Iron removing rate is 90%.

常用除铁方法主要有 [1 ，2 ] ：(1 )直接鼓风氧化生成针铁矿的形式除铁；(2 )用生成磷酸盐沉淀的方法除铁；(3 )用黄钾铁矾法除铁；(4)用过氧化氢氧化除铁；(5 )采用溶剂萃取法分离铁。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
