锰离子 meaning in Chinese
manganese ion
Examples
- Water quality - determination of dissolved li , na , nh 4 , k , mn 2 , ca 2 , mg 2 , sr 2 and ba 2 using ion chromatography - method for water and waste water
水质.用离子色谱法测定锂离子钠离子铵离子钾离子锰离子钙离子镁离子锶离子和钡离子含量.适用于水和废水的方法 - Compared with limn2o4 , li2mn2o4 has lower reversible capacity , in that the net charge of lithium ion increases , accordingly interactions between lithium ion and oxygen one strengthen , leading to difficulty for lithium ion to deintercalate
Li2mn2o4与limn2o4相比，锰离子的净电荷几乎不变，表明锰离子与氧离子的相互作用变化不大，大部分锂离子和氧离子的相互作用增强，锂离子脱出较为困难，可逆容量降低。 - The results show that the composition of these precursors are identified to be limn2l ( ac ) 2 ( or ltmn2c10h11o11 ) , in which l represents citric acid radical and ac is acetic acid radical . the sintering temperature and sintering time have remarkable effects on the microstructures of limn2o4 samples
结果表明通过低热固相反应法可在全固相条件下得到锂离子与锰离子达到分子级混合水平的前驱体，其组成基本上与分子式limn _ 2c _ ( 10 ) h _ ( 11 ) o _ ( 11 )相吻合。 - It revealed that hexagonal structure was easily synthesized in the neutral medium , and lamellar structure was inclined to prepare under basic condition , and from the cooperative charge density matching mechanism and function of manganese iron and template molecular , the alkalescence influence on the structure was explained , and appropriate neutral hexadecylamine ( hda ) availed to synthesis of mesophase with more ordered degree for the mediation of packing parameter
通过水热合成方法对锰氧有序相的合成进行初步研究，探讨合成工艺对有序结构的影响：在中性的条件下，易合成六方有序结构产物；在碱性条件下，更易合成层状结构产物。并从电荷匹配的原则及锰离子与模板剂间键合作用解释了碱量的多少对合成产物结构的影响。 - The effort of manganese removal was studied and the kinetics of manganese removal was tried to establish . the factors of dissolved oxygen concentration , fe2 + concentration , ph , p concentration and closing of the filter were studied to evaluate their effort for biological manganese removal , and the correlation of residual manganese and oxidation - reduction potential was also discussed . as the iron content of water was high , experiment results showed that the reaction was zero order , as the iron content of water was low , the reaction was first order . the time needed for the cultivation of biological manganese removal was 60 70 days . the filter operated at the filtration rate of 8 10m / h , silica sand of effective size 0 . 95 1 . 25mm filled the filter to a depth of 1200mm
试验结果表明,成熟后滤砂表面滤膜的x射线衍射图谱与mno _ x ? 5h _ 2o ( x = 1 . 86 )的x射线衍射图谱一样,滤膜成熟后的结构在进水物质不发生变化的情况下不发生变化;合适的碳磷比对生物除锰有明显的促进作用,试验条件下的投磷量不会对出水造成二次污染;生物除锰需要亚铁的参与,亚铁的存在除了能够促进微生物分泌胞外酶并刺激其活性外,还通过铁离子的变价传递电子,催化锰离子的氧化反应,从而促进对二价锰的降解。
