過硫酸銨呈白色晶體粉末狀，常常會作為引發劑，在化學反應中引發聚合反應。然而有的時候過硫酸銨會出現失效的情況，那么，這是為什么呢？過硫酸銨在使用的時候一定要現配現用嗎？過硫酸銨在使用的時候還需要注意哪些呢？接下來可以和小編一起了解一下。

Ammonium persulfate is a white crystalline powder, often used as an initiator to initiate polymerization in chemical reactions. However, sometimes ammonium persulfate will fail, so why? Does ammonium persulfate have to be prepared and used now? What else should we pay attention to when using ammonium persulfate? Next, we can learn about it with Xiaobian.

過硫酸銨在使用的時候是需要現配現用的。已經配置了15%的過硫酸銨溶液放置時間過長就會失效，是由于過硫酸銨在水中溶解較快，并且在室溫下，其穩定性差，即使在避光或無空氣的情況下，也能在水溶液中被水解為硫酸氫銨和過氧化氫，后者分解為水和氧氣。在鹽的作用下，雙氧水更易于被破壞。因此，長期使用的過硫酸銨溶液就會失去作用。

When ammonium persulfate is used, it needs to be prepared and used. The 15% ammonium persulfate solution that has been prepared will fail if it is stored for a long time, because ammonium persulfate dissolves quickly in water, and its stability is poor at room temperature. Even in the absence of light or air, it can be hydrolyzed into ammonium bisulfate and hydrogen peroxide in aqueous solution, and the latter can be decomposed into water and oxygen. Hydrogen peroxide is easier to be destroyed under the action of salt. Therefore, the ammonium persulfate solution used for a long time will lose its function.

過硫酸銨的變質的因素是由于它在室溫下會在水中溶解，而在常溫下，固體的過硫酸銨穩定性很好，只要不在高溫、潮濕和強光條件下，它就能一直儲存。

The deterioration factor of ammonium persulfate is that it will be dissolved in water at room temperature. At room temperature, the solid ammonium persulfate is very stable. As long as it is not under high temperature, humidity and strong light, it can be stored all the time.

過硫酸銨操作時避免產生粉塵。避免與還原劑、活性金屬粉末接觸。搬運時要輕裝輕卸，防止包裝及容器損壞。禁止震動、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。

Avoid dust during ammonium persulfate operation. 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. Provide fire fighting equipment and leakage emergency treatment equipment of corresponding types and quantities. Empty containers may contain harmful substances.

在使用過硫酸銨的過程中，應避免產生粉塵。避免接觸還原劑，活性金屬粉末。運輸時應輕放輕放，避免包裝和容器的損傷。禁止振動、碰撞以及摩擦。配備相應種類和數量的滅火設備，以及緊急情況下的處置設施。傾倒后的容器中可能會存在有害物質殘留，需要及時處理。

In the process of using ammonium persulfate, dust should be avoided. Avoid contact with reducing agent and active metal powder. Handle with care during transportation to avoid damage to packaging and containers. Vibration, collision and friction are prohibited. Provide corresponding types and quantities of fire extinguishing equipment and disposal facilities in case of emergency. There may be residual harmful substances in the dumped container, which needs to be disposed in time.
