摘要: A process is disclosed for the separation of hydrogen cyanide from gases and waste gases by a throughflow or circulation scrubbing, in which formaldehyde is added at a controlled rate to the aqueous scrubbing liquid to form glycol nitrile. This addition is controlled by measuring the HCN tension in a measuring stream which has been branched off and which is first treated with hydrogen peroxide so that free H.sub.2 O.sub.2 is still detectable after 1 to 100 seconds and the pH is adjusted to a constant value before measurement of the HCN tension is carried out. The process prevents overdosing with formaldehyde which could not always be prevented in previously known processes in which the addition of formaldehyde was regulated by measuring the cyanide specific redox potential.
摘要翻译: 公开了一种通过通流或循环洗涤从气体和废气中分离氰化氢的方法,其中将甲醛以受控的速率加入到水洗涤液中以形成二醇腈。 该添加通过测量已经分支并且首先用过氧化氢处理的测量流中的HCN张力来控制,使得在1至100秒之后仍然可以检测到游离H 2 O 2,并且在测量之前将pH调节至恒定值 HCN张力进行。 该方法防止了甲醛过量,这在以前已知的通过测量氰化物特定的氧化还原电位来调节甲醛的方法中是不可避免的。

摘要: The content of halo-organic pollutants in water is lowered to residual AOX values below 1 mg/l, preferably below 0.1 mg/l by adjusting the Fe.sup.2+ comtent of the water to 20 to 1000 mg/l, adding a precipitated or pyrogenic silicic acid, converting 20 to 1000 mg of the Fe.sup.2+ into Fe.sup.3+ by adding in an oxidation agent, preferably hydrogen peroxide, and separating the iron (III) hydroxy complexes formed and the silicic acid, which contain the halo-organic pollutants in an adsorbed state, at pH 5-10. The method can be controlled in a simple manner as regards the addition of Fe.sup.2+ and oxidation agent via the Fe.sup.2+ /Fe.sup.3+ redox potential.
