试样以盐酸溶解后，在酸性介质中，先以氯化亚锡将三价铁大部分还原为二价，然后在钨酸钠指示下，再以三氯化钛将剩余的三价铁还原为二价，过量的三氯化钛以重铬酸钾氧化消除干扰，在硫磷混合酸存在下，以二苯胺磺酸钠为指示剂，用重铬酸钾标准溶液滴定全铁量。

Cyclic voltammetry indicated that there were Cr→Cr, Cr →Cr oxidation reaction on anode, while there were Cr→Cr, Cr→Cr, Cr →Cr deoxidization reaction on cathode. The graphite electrodes treated by acid and heating could enhance the reversibility and kinetic of the electrode reaction. The nature graphite electrodes had been eroded during charge/discharge process, while the graphite electrodes by activation could avoide corroding by hexad chromium ion. The reversibility and kinetic of the electrode reaction of chromium ion on activation electrode had been increased, so which indicated that graphite surface augment oxygenous function corps which could increase electrode hydrophile capability.

循环伏安实验表明：铬液流电池的电极反应非常复杂，在阳极存在Cr→Cr，Cr→Cr的氧化反应，在阴极存在Cr→Cr，Cr→Cr，Cr→Cr的还原反应；热处理的石墨电极和重铬酸钾处理的石墨电极能提高电极反应的活性和可逆性；在充放电实验中未处理的石墨电极发生严重腐蚀；分别用这两种方法处理过的石墨电极具有防止六价铬侵蚀的功能；铬离子在活化处理过的石墨电极上的反应活性和可逆性增加，可以认为：重铬酸钾溶液活化处理和加热处理后的石墨表面的含氧官能团增加，电极亲水性增强。

Potassium dichromate K 2 Cr 2 O 7 or ammonium dichromate (NH 4 ) 2 Cr 2 O 7 for AN based mixtures.

重铬酸钾钾铬2 O的7或铵重铬酸钾（信息NH 4 ） 2铬2 O的七月为一基于混合物。

In the experiment, the study on result of measurement of COD by potassium dichromate method has been conducted in the aspect of impact and application scope, proposing the method of measuring low COD in waste water of high chlorine and putting forward new comment on its influence factor.

本试验采用重铬酸钾标准法对COD测定结果的影响程度与适用范围进行了探索，提出了用低浓度重铬酸钾氧化法测定含高氯根废水中低COD的方法，对其影响因素提出新的看法。

This method is fast,accurate,simple and is used to the routine check of the metallic iron in sponge iron with satisfactory result.

介绍了用三氯化铁-重铬酸钾容量法测定海绵铁中金属铁的方法，试样用三氯化铁溶液选择性地使金属铁溶解，过滤分离不溶物，移取部分滤液，用重铬酸钾容量法直接滴定，方法快速准确，操作简便，用于海绵铁中金属铁的日常检测，可获得满意结果。

The effect of bacteriostatic such as penicillin, norfloxacin, nalidixic acid, potassium dichromate and tatin were studied individually. The orthogonal design was used in this experiment and the software STATISTICA6.0 was employed to analyse the result. The result showed that the potassium dichromate was the best bacteriostatic among those bacteriostatices.
