氫氧化鉀廢棄后怎么處置合適？這是很多人想知道的一個(gè)問題，畢竟該產(chǎn)品不能隨意丟棄，處理妥當(dāng)是必要的，下面來看看吧。
　　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.
　　氫氧化鉀使用過后的容器不要隨意丟棄應(yīng)該集中處理，因?yàn)樵摦a(chǎn)品具有一定的腐蝕性，如果容器上有殘留會(huì)造成污染。還有使用過程中如果殘留剩余原料也要進(jìn)行集中處理。
　　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.
　　廢棄處置的要點(diǎn)主要有以下內(nèi)容：
　　The main points of waste disposal are as follows:
　　禁止：不應(yīng)釋放進(jìn)環(huán)境。不要與其他危險(xiǎn)廢物一起處理。處置建議：緩慢加入酸液并不斷攪拌進(jìn)行中和，反應(yīng)停止后，用大量水稀釋沖入廢水系統(tǒng)。
　　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.
　　應(yīng)避免的廢物處置方式：不得在產(chǎn)品殘留清洗前毀掉容器。污染包裝物：根據(jù)當(dāng)?shù)丨h(huán)境法規(guī)要求進(jìn)行操作。其他理化性質(zhì)：按當(dāng)?shù)匾?guī)定處理。
　　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.
　　氫氧化鉀廢棄處置應(yīng)符合當(dāng)?shù)丨h(huán)保的要求，并且要求有專業(yè)的地方進(jìn)行集中處理，禁止掩埋處理，避免造成各方面的麻煩。
　　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.

　　溶解氫氧化鉀的具體步驟：
　　Specific steps to dissolve potassium hydroxide:
　　配0.1mol/L氫氧化鉀，就稱5.6g氫氧化鉀，氫氧化鉀溶液不能直接把氫氧化鉀固體放入容量瓶中，因?yàn)闅溲趸浫苡谒畷?huì)劇烈放熱，所以應(yīng)該將稱取的一定質(zhì)量的氫氧化鉀放入小燒杯中；
　　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;
　　然后向其中緩緩注入已煮沸除去CO2并已冷卻的蒸餾水/去離子水，并不斷用玻璃棒攪拌使氫氧化鉀固體完全溶解；
　　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;
　　待其自然冷卻后，用玻棒引流導(dǎo)入容量瓶中，再用已煮沸除去CO2并已冷卻的蒸餾水/去離子水洗滌玻棒及燒杯3~4次并將洗液注入容量瓶中，再對容量瓶進(jìn)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.
　　注意在溶解的過程中：把固體氫氧化鉀往水里加，一邊加一邊拌和，避免部分過熱，直到徹底溶解；少數(shù)溶解時(shí)是不會(huì)濺出來的，在進(jìn)行溶解時(shí)有必要是將堿參加水中，制止將水參加堿中。其容器選用塑料原料的；若是需求固定容量的話，水少一點(diǎn)，等溶解完后，冷卻，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.
