高锰酸钾

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。

Here, we supposed that the manganese and singlet oxygen coexisted in the acid potassium permanganate system.

石灰或草木灰塘施或对水浇施，腐熟农家肥和石灰或高锰酸钾配合使用对根肿病的发生均有较好的抑制作用；单施农家肥和高锰酸钾对根肿病控制效果不理想，用腐熟农家肥作底肥＋1%石灰水播种后浇塘＋1%石灰水三叶期浇根＋1%石灰水六叶期再浇根的组合模式可以有效地控制对根肿病的发生与危害。

And then, the second-order reaction rate constant was K =0.025 L/. The removal of ethanethiol in raw water by potassium permanganate under coagulation condition was poorer than in pure water condition, So predicted concentration of potassium permanganate was lower than real concentration.

高锰酸钾在原水混凝条件下对乙硫醇的去除效果劣于纯水条件下的去除效果，在水中其它有机物与高锰酸钾反应条件下高锰酸钾浓度变化的拟合结果与实际情况存在偏差，是产生差异的主要原因。

The color removal of azo dye Acid Orange Ⅱ using potassium permanganate was studied. The effect of Acid Orange Ⅱ and potassium permanganate concentration, initial pH conditions, and reaction time were investigated.

METHODS By nested polymerase chain reaction, the inactivation efficacy of three different concentrations of iodophor, potassium permanganate, Lysol,"84" disinfectant and jingxin liquid disinfectant was detected after TTV having been disinfected for 10, 30, 60 and 90 minutes by these disinfectants respectively.

采用巢式聚合酶链反应技术，检测 3种不同浓度的碘伏、高锰酸钾、煤酚皂液、&84&消毒液和金星消毒剂，对 TTV DNA分别消毒处理 10、30、6 0 min和 90 m in的灭活效果。结果碘伏在常规使用浓度(0 。5 %～ 1%)对 TTV DNA灭活效果好；高锰酸钾、来苏尔、&84&消毒液和金星消毒剂在高浓度下可灭活 TTV DNA ，而常规使用浓度对 TTV DNA灭活效果不好。

In this study, the early stage development of Japanese medaka was used to assess the toxic effects of potassium permanganate and its byproduct Mn(superscript 2+) in the drinking water process.

Iodine in the test solution was oxidized to IO-3 by excessive amounts of potassium permanganate solution and sodium hypochlorite solution,and excess of the oxidants was removed by reacting with sodium sulfite solution.

采用过量联合氧化剂高锰酸钾-次氯酸钠氧化试液中碘至IO3-，剩余的高锰酸钾和次氯酸钠用过量的亚硫酸钠反应除去，利用IO3-的电活性，建立了在四硼酸钠-吐温-80底液中的线性扫描伏安法测定微量碘的方法。

The changes of complex permittivity of pure-water,natrium oxalate,potassium permanganate and sodium chloride aqueous solution with different power were measured.It is shown that the changes of real part of the complex permittivity are all small and the imaginary part of the complex permittivity of electrolyte solution are obvious.

通过实验分别测量了纯水、草酸钠、高锰酸钾和氯化钠水溶液的复介电常数随微波测量功率改变的情况，发现4种待测物质的复介电常数实部都随微波功率改变较小，而草酸钠、高锰酸钾和氯化钠水溶液的复介电常数虚部随微波功率改变明显。
