Manganate ion-sieves are excellent absorbents for lithium because of their specificity and low-toxicity to environment. They are highly applicable to extract lithium in brine.

中文摘要锰酸盐型锂离子筛对锂离子具有选择吸附性，并且环境友好，在盐湖卤水提锂工艺上有很高的应用价值和广阔的应用前景。

The potassium permanganate is one kind of important manganese compound,its preparation is mainly melts the oxo-process with the solid phase alkali at present,take the potassium manganate as the intermediary to make.

是化学方面的，写论文用。急用！问题补充：下面这段：高锰酸钾是一种重要的锰的化合物，它的制备目前主要是用固相碱熔氧化法，以锰酸钾为中间产物来制备。

Vemadite and 1 nm manganate are the two main manganates in the polymetallic nodules, they both have the characteristic X ray diffraction pattern in 0.24 nm and 0.14 nm, therefore much attention should be paid in order to distinguish these two manganates during mineral analysis.

水羟锰矿和1nm锰矿相是多金属结核中最主要的两种锰矿物，它们两者均有0.24nm和0.14nm这两条特征X射线衍射峰，因此在对结核进行锰矿物相的鉴定中要注意把它们区分开。

For some EN baths significant precipitation of the metal ions can only occur after thecomplexing agent has been substantially removed by either biological oxidation or chemical oxidation using ozone, potassium manganate, sodium hypochloriteor hydrogen peroxide .

对于一些恩浴金属离子的显着降水后只能出现络合剂已大为拆除或化学或生物氧化利用臭氧氧化，钾锰，次氯酸钠或过氧化氢。

The crystal structure of the marine 1 nm manganate is quite different with that of the land base todorokite, and it has more similarities with the synthetic 1 nm manganate of buserite instead, therefore the marine 1 nm manganate and todorokite are the distinct manganates. The 1 nm manganate can be transformed into 0.7 nm manganate by losing some water caused by drying, and the 0.7 nm manganate might not be the original manganate phase in polymetallic nodules, but is more likely to be the phase transformation product of 1 nm manganate.

大洋多金属结核中的1nm锰矿相常以陆上钡镁锰矿命名，但两者在晶体结构等方面有很大的差别，并不属同一种矿物，1nm锰矿相与人工合成的布塞尔矿却有更多的相似性。1nm锰矿相会因干燥失水而相变成0.7nm锰矿相，因此结核中的大多数0.7nm锰矿相很可能不是原生矿物，而仅仅是1nm锰矿相的相变产物。

The invention discloses a method for measuring seawater chemical oxygen demand by photometry, wherein the seawater exemplar is first pre-processed, then using the basic potassium hypermanganate as reaction system, the potassium permanganate is deacidized quantitatively by organics to produce manganate, using pure water or margin solution as reference ratio, measuring the absorbance an of the manganate at its maximum absorbing wave length 430 nm, drafting the A-COD value operating curve, obtaining the concentration of the organics in the water, i.e.

本发明公开了一种对海水化学需氧量进行测定的光度测定法，该方法首先将海水样品进行预处理，再以碱性高锰酸钾为反应体系，这样海水中的有机物在强碱性介质中与过量的高锰酸钾迅速反应，高锰酸钾被有机物定量还原后生成锰酸盐，以纯水或空白溶液作参比，在锰酸盐的最大吸收波长430nm处测其吸光度A，该吸光度A与海水样品中的有机物的含量具有正相关关系。

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。
