過(guò)硫酸銨是氧化劑還是還原劑

更新時(shí)間:2022-11-09 點(diǎn)擊數:1993

很多人對過(guò)硫酸銨是氧化劑還是還原劑存在疑惑,實(shí)際上氫氧化鉀廠(chǎng)家可以明確告訴您過(guò)硫酸銨是氧化劑。

Many people have doubts about whether ammonium persulfate is an oxidant or a reductant. In fact, potassium hydroxide manufacturers can tell you that ammonium persulfate is an oxidant.

過(guò)二硫酸根含有過(guò)氧基,是強氧化劑,可以把Mn2+氧化為MnO4-。

Persulfate contains peroxy group and is a strong oxidant, which can oxidize Mn2+to MnO4 -.

所以過(guò)硫酸銨溶液中除了大量的銨根離子和過(guò)二硫酸根離子外,還存在少量的硫酸氫根離子和硫酸根離子,溶液水解顯酸性,加入硝酸可以抑制反應正向進(jìn)行。

Therefore, in addition to a large amount of ammonium ions and persulfate ions, there are also a small amount of hydrogen sulfate ions and sulfate ions in the ammonium persulfate solution. The solution is acidic when hydrolyzed, and adding nitric acid can inhibit the reaction from going forward.

密閉操作,局部排風(fēng)。操作人員須經(jīng)過(guò)專(zhuān)門(mén)培訓,嚴格遵守操作規程。建議操作人員佩戴頭罩型電動(dòng)送風(fēng)過(guò)濾式防塵呼吸器,穿聚乙烯防毒服,戴橡膠手套。遠離火種、熱源,工作場(chǎng)所嚴禁吸煙。避免產(chǎn)生粉塵。避免與還原劑、活性金屬粉末接觸。搬運時(shí)要輕裝輕卸,防止包裝及容器損壞。禁止震動(dòng)、撞擊和摩擦。配備相應品種和數量的消防器材及泄漏應急處理設備。倒空的容器可能殘留有害物。

It is recommended that the operator wear a hood type electric air supply filter type dust respirator, polyethylene gas protective clothing and rubber gloves. Keep away from kindling and heat sources. Smoking is strictly prohibited in the workplace. Avoid dust generation. Avoid contact with reducing agent and active metal powder. Handle with care to prevent damage to packaging and containers. Vibration, impact and friction are prohibited. Fire fighting equipment and leakage emergency treatment equipment of corresponding varieties and quantities shall be provided. Empty containers may retain harmful substances.

儲存于陰涼、干燥、通風(fēng)良好的庫房。遠離火種、熱源。包裝須密封,防止受潮。應與還原劑、活性金屬粉末等分開(kāi)存放,切忌混儲。儲區應備有合適的材料收容泄漏物。塑料袋或二層牛皮紙袋外全開(kāi)口或中開(kāi)口鋼桶;塑料袋或二層牛皮紙袋外普通木箱;螺紋口玻璃瓶、鐵蓋壓口玻璃瓶、塑料瓶或金屬桶(罐)外普通木箱。

Store in a cool, dry and well ventilated warehouse. Keep away from kindling and heat source. The package must be sealed to prevent moisture. It shall be stored separately from reductant, active metal powder, etc., and shall not be mixed. The storage area shall be equipped with appropriate materials to contain the leakage. Full opening or middle opening steel barrel outside the plastic bag or two-layer kraft paper bag; Ordinary wooden case outside plastic bag or two-layer kraft paper bag; Screw mouth glass bottle, iron cap pressure mouth glass bottle, plastic bottle or ordinary wooden box outside metal barrel (can).

運輸時(shí)車(chē)速不宜過(guò)快,不得強行超車(chē)。運輸車(chē)輛裝卸前后,均應清掃、洗凈,嚴禁混入有機物、易燃物等雜質(zhì)。安全為重,希望您有所了解

During transportation, the speed should not be too fast, and forced overtaking is not allowed. Before and after loading and unloading of transport vehicles, they shall be cleaned and cleaned. It is strictly prohibited to mix organic substances, inflammables and other impurities. Safety is the most important. I hope you can learn more about it.
