decolour
1.The decolour reaction of HCPCF with IO?-?3 in acid medium is reported.
3.Law of coloring of change orchid family name, can be bacterial cent two kinds big: Use method of this kind of coloring, it is to use gentian to catch a bug first, all bacteria caught purple, besmear again next with iodic fluid, will strengthen the tie of dye and bacterium body, the alcohol of 95 ％ comes to reoccupy decolour 20 ～ 30 seconds, some bacteria not by decolour, still withhold purple, some bacteria are become by decolour colorless, reoccupy answer is red finally answer catch 1 minute, the result already was caught by the bacterium of decolour Cheng Gong is lubricious, not the bacterium of decolour still keeps purple, no longer chromatic, such, every is caught purple bacterium calls bacterium of positive of change orchid family name; Ran Chenggong calls bacterium of negative of change orchid family name lubriciously.
4.Also through handing in and testing the law and optimizing various kinds of factors of dealing with result of influencing,the experimental result shows : Unless it look on by dyestuffs as it is initial density for160 mg/L,unless pH in the 8 about,waste residue and proportion is for 2:1 fly ash,total amount is 1g,under 2.5 hour terms,above 90% to decolour rate the time of staying,the result is obvious.
