氢氧化钾废弃后怎么处置合适？这是很多人想知道的一个问题，毕竟该产品不能随意丢弃，处理妥当是必要的，下面来看看吧。

　　How to dispose of potassium hydroxide after waste? This is a question many people want to know, after all, the product can not be thrown away at will, it is necessary to deal with properly, take a look below.

　　氢氧化钾使用过后的容器不要随意丢弃应该集中处理，因为该产品具有一定的腐蚀性，如果容器上有残留会造成污染。还有使用过程中如果残留剩余原料也要进行集中处理。

　　Potassium hydroxide containers after use should not be discarded at will and should be centrally disposed of, because this product is corrosive to a certain extent, if there is residue on the container will cause pollution. There is also the use of residual raw materials should be centralized processing.

　　废弃处置的要点主要有以下内容：

　　The main points of waste disposal are as follows:

　　禁止：不应释放进环境。不要与其他危险废物一起处理。处置建议：缓慢加入酸液并不断搅拌进行中和，反应停止后，用大量水稀释冲入废水系统。

　　Prohibited: should not be released into the environment. Do not dispose with other hazardous wastes. Disposal suggestion: Add acid slowly and stir continuously for neutralization. After the reaction stops, dilute it with a large amount of water and flush it into the wastewater system.

　　应避免的废物处置方式：不得在产品残留清洗前毁掉容器。污染包装物：根据当地环境法规要求进行操作。其他理化性质：按当地规定处理。

　　Waste disposal to avoid: Do not destroy containers before product residue cleaning. Contaminated packaging: Operate in accordance with local environmental regulations. Other physical and chemical properties: according to local regulations.

　　氢氧化钾废弃处置应符合当地的要求，并且要求有的地方进行集中处理，禁止掩埋处理，避免造成各方面的麻烦。

　　Potassium hydroxide waste disposal should meet the requirements of local environmental protection, and require a professional place for centralized treatment, no burial treatment, to avoid all aspects of trouble.

　　溶解氢氧化钾的具体步骤：

　　Specific steps to dissolve potassium hydroxide:

　　配0.1mol/L氢氧化钾，就称5.6g氢氧化钾，氢氧化钾溶液不能直接把氢氧化钾固体放入容量瓶中，因为氢氧化钾溶于水会剧烈放热，所以应该将称取的一定质量的氢氧化钾放入小烧杯中；

　　With 0.1mol/L potassium hydroxide, it is called 5.6g potassium hydroxide. Potassium hydroxide solution can not be directly put into a volumetric flask, because potassium hydroxide dissolved in water will be violent heat release, so it should be weighed into a certain mass of potassium hydroxide into a small beaker;

　　然后向其中缓缓注入已煮沸除去CO2并已冷却的蒸馏水/去离子水，并不断用玻璃棒搅拌使氢氧化钾固体完全溶解；

　　Then slowly inject distilled water/deionized water, which has been boiled to remove CO2 and has been cooled, into it, and constantly stir with a glass rod to completely dissolve the solid potassium hydroxide;

　　待其自然冷却后，用玻棒引流导入容量瓶中，再用已煮沸除去CO2并已冷却的蒸馏水/去离子水洗涤玻棒及烧杯3~4次并将洗液注入容量瓶中，再对容量瓶进行定容。

　　After its natural cooling, the glass rod is drained into the volumetric flask, and then the glass rod and beaker are washed with boiled and cooled distilled water/deionized water to remove CO2 for 3-4 times, and the lotion is injected into the volumetric flask, and then the volumetric flask is fixed.

　　注意在溶解的过程中：把固体氢氧化钾往水里加，一边加一边拌和，避免部分过热，直到彻底溶解；少数溶解时是不会溅出来的，在进行溶解时有必要是将碱参加水中，制止将水参加碱中。其容器选用塑料原料的；若是需求固定容量的话，水少一点，等溶解完后，冷却，再用水定容就好了。

　　Note in the process of dissolution: add solid potassium hydroxide into water and mix it together to avoid overheating until it is completely dissolved; A small number of dissolved is not splashed out, in the process of dissolution is necessary to join the alkali in water, to prevent water in the alkali. The containers are made of plastic materials; If the need for fixed capacity, a little less water, such as dissolved, cooling, and then water constant volume is good.
