过硫酸铵呈白色晶体粉末状，常常会作为引发剂，在化学反应中引发聚合反应。然而有的时候过硫酸铵会出现失效的情况，那么，这是为什么呢？过硫酸铵在使用的时候一定要现配现用吗？过硫酸铵在使用的时候还需要注意哪些呢？接下来可以和小编一起了解一下。

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.

过硫酸铵在使用的时候是需要现配现用的。已经配置了15%的过硫酸铵溶液放置时间过长就会失效，是由于过硫酸铵在水中溶解较快，并且在室温下，其稳定性差，即使在避光或无空气的情况下，也能在水溶液中被水解为硫酸氢铵和过氧化氢，后者分解为水和氧气。在盐的作用下，双氧水更易于被破坏。因此，长期使用的过硫酸铵溶液就会失去作用。

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.

过硫酸铵的变质的因素是由于它在室温下会在水中溶解，而在常温下，固体的过硫酸铵稳定性很好，只要不在高温、潮湿和强光条件下，它就能一直储存。

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.

过硫酸铵操作时避免产生粉尘。避免与还原剂、活性金属粉末接触。搬运时要轻装轻卸，防止包装及容器损坏。禁止震动、撞击和摩擦。配备相应品种和数量的消防器材及泄漏应急处理设备。倒空的容器可能残留有害物。

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.

在使用过硫酸铵的过程中，应避免产生粉尘。避免接触还原剂，活性金属粉末。运输时应轻放轻放，避免包装和容器的损伤。禁止振动、碰撞以及摩擦。配备相应种类和数量的灭火设备，以及紧急情况下的处置设施。倾倒后的容器中可能会存在有害物质残留，需要及时处理。

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.
