过硫酸铵的操作需要注意什么?

更新时间:2021-12-30 点击数:472

过硫酸铵作为氧化剂和漂白剂,被广泛地用于蓄电池工业;它还用作聚合的引发剂、纤维工业的脱浆剂; 并可用作金属及半导体材料表面处理剂、印刷线路的刻蚀剂; 还广泛用于石油开采的油层压裂, 面粉和淀粉加工业、油脂工业, 在照相工业上用来除去海波。

Ammonium persulfate is widely used in battery industry as oxidant and bleach; It is also used as initiator for polymerization and desizing agent for fiber industry; It can also be used as surface treatment agent for metal and semiconductor materials and etching agent for printed circuits; It is also widely used in oil reservoir fracturing, flour and starch processing industry, oil industry, and photographic industry to remove sea waves.

英文别名:Ammonium persulfate ,APS ,PER

English alias: ammonium persulfate, APS, per

性状:白色结晶或粉末。无气味。干燥纯品能稳定数月,受潮时逐渐分解放出含臭氧的氧,加热则分解出氧气而成为焦硫酸铵。易溶于水,水溶液呈酸性,并在室温中逐渐分解,在较高温度时很快分解放出氧气,并生成硫酸氢铵。相对密度1.98。低毒,半数致死量(大鼠,经口)820mG/kG。有强氧化性,与有机物摩擦或撞击,能引起燃烧。有腐蚀性。

Properties: white crystal or powder. No smell. The dry pure product can be stable for several months. When it is wet, it will gradually decompose into oxygen containing ozone, and when heated, it will decompose into oxygen and become ammonium pyrosulfate. It is easily soluble in water. The aqueous solution is acidic and decomposes gradually at room temperature. At higher temperature, it decomposes quickly to release oxygen and produce ammonium bisulfate. Relative density 1.98. Low toxicity, LD50 (rat, oral) 820mg / kg. It has strong oxidation, can cause combustion by friction or impact with organic matter. It is corrosive.

储存:密封阴凉干燥保存。防止与有机物接触。

Storage: sealed, cool and dry. Prevent contact with organic matter.

过硫酸铵用途:检定和测定锰,用作氧化剂。漂白剂。照相还原剂和阻滞剂。电池去极剂。用于可溶性淀粉的制备。

Ammonium persulfate uses: verification and determination of manganese, used as oxidant. bleaching agents. Photographic reductants and blockers. Battery depolarizer. It is used for the preparation of soluble starch.

应急处理: 隔离泄漏污染区,限制出入。建议应急处理人员戴防尘面具(全面罩),穿防毒服。不要直接接触泄漏物。勿使泄漏物与还原剂、有机物、易燃物或金属粉末接触。小量泄漏:用砂土、干燥石灰或苏打灰混合。收集于干燥、洁净、有盖的容器中。也可以用大量水冲洗,洗水稀释后放入废水系统。大量泄漏:收集回收或运至废物处理场所处置。

Emergency treatment: isolate the leakage contaminated area and restrict access. It is recommended that emergency treatment personnel wear dust masks (full cover) and wear anti poison clothing. Do not directly contact the leakage. Do not contact the leakage with reducing agent, organic matter, inflammables or metal powder. Small leakage: mix it with sand, dry lime or soda ash. Collect it in a dry, clean and covered container. It can also be washed with a large amount of water and diluted with washing water and then put it into the wastewater system. Large leakage: collect, recycle or transport it to Waste disposal site.

过硫酸铵操作注意事项: 密闭操作,局部排风。操作人员必须经过专门培训,严格遵守操作规程。建议操作人员佩戴头罩型电动送风过滤式防尘呼吸器,穿聚乙烯防毒服,戴橡胶手套。远离火种、热源,工作场所严禁吸烟。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。

Precautions for ammonium persulfate operation: closed operation, local exhaust. Operators must receive special training and strictly abide by the operating procedures. It is recommended that operators wear hooded electric air supply filter dust respirator, polyethylene anti-virus 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. Provide corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. Emptied containers may leave harmful substances.

储存注意事项: 储存于阴凉、干燥、通风良好的库房。远离火种、热源。包装必须密封,防止受潮。应与还原剂、活性金属粉末等分开存放,切忌混储。储区应备有合适的材料收容泄漏物。

Storage precautions: store in a cool, dry and well ventilated warehouse. Keep away from fire and heat source. The package must be sealed to prevent moisture. It shall be stored separately from reducing agent and active metal powder, and mixed storage shall not be allowed. The storage area shall be provided with suitable materials to contain leakage.
