海外npv加速器试用存放时间：海外npv加速器试用作为氧化剂，应避免与还原性物质、硫、磷等混合存放，且要放在干燥的地方，不能存放太久。

Storage time of Potassium persulfate: as an oxidant, Potassium persulfate should not be mixed with reducing substances, sulfur, phosphorus, etc., and should be stored in a dry place.

海外npv加速器试用溶液更不能长期存放，标准中规定碱性海外npv加速器试用溶液在聚乙烯瓶中存放不能超过 7 d。碱性海外npv加速器试用在27～30 ℃ 环境下，存放超过3 d，空白值就会大于0. 030 建议实验时尽量根据近 3 d 的需求量配制，存放尽量不要超过3 d。

Potassium persulfate solution can not be stored for a long time, and the standard stipulates that alkaline Potassium persulfate solution can not be stored for more than 7 days in a polyethylene bottle. When alkaline Potassium persulfate is stored at 27~30 ℃ for more than 3 days, the blank value will be greater than 0 It is recommended to prepare according to the demand for nearly 3 days during the experiment and store it for no more than 3 days.

海外npv加速器试用溶液存放条件

Storage conditions of Potassium persulfate solution

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。包装密封。应与还原剂、活性金属粉末、碱类、醇类等分开存放，切忌混储。

Storage precautions: Store in a cool, dry, and well ventilated warehouse. Keep away from sparks and heat sources. Packaging sealing. It should be stored separately from reducing agents, active metal powders, alkalis, alcohols, etc., and mixed storage should be avoided.

海外npv加速器试用溶液保质期：一周。海外npv加速器试用具有强氧化性，不稳定，易分解，放出氧变为焦硫酸钾，100℃时完全分解，其溶液长期贮存浓度会改变。

Shelf life of Potassium persulfate solution: one week. Potassium persulfate is highly oxidizing, unstable, and easy to decompose. It emits oxygen and becomes Potassium pyrosulfate, which will be completely decomposed at 100 ℃, and its solution concentration will change after long-term storage.

抗坏血酸溶液保质期：两周。由于抗坏血酸溶液易被氧化，通常加抗氧化剂如PVP，巯基乙醇等能维持稳定抗坏血酸溶液喜酸怕碱，高温和强光下会被氧化，所以尽量低温使用不透光的瓶子保存通常冷藏避光条件下，存放时间不宜超过半年。

Shelf life of ascorbic acid solution: two weeks. Due to the susceptibility of ascorbic acid solutions to oxidation, the addition of antioxidants such as PVP and mercaptoethanol can maintain stability. The ascorbic acid solution is acid sensitive and alkali resistant, and can be oxidized under high temperatures and strong light. Therefore, it is recommended to use opaque bottles at low temperatures for storage. Generally, under refrigerated and dark conditions, the storage time should not exceed six months.

监测方法

Monitoring methods

工程控制：生产过程密闭，加强通风。提供淋浴和洗眼设备。

Engineering control: The production process is sealed and ventilation is strengthened. Provide safety showers and eye wash equipment.

呼吸系统防护：可能接触其粉尘时，应该佩戴头罩型电动送风过滤式防尘呼吸器。高浓度环境中，建议佩戴自给式呼吸器。

Respiratory system protection: When there is a possibility of contact with its dust, a hood type electric air supply filter type dust respirator should be worn. In high concentration environments, it is recommended to wear a self-contained breathing apparatus.

眼睛防护：呼吸系统防护中已作防护。

Eye protection: Protective measures have been taken in respiratory system protection.

身体防护：穿聚乙烯防毒服。

Body protection: Wear polyethylene protective clothing.

手防护：戴橡胶手套。

Hand protection: Wear rubber gloves.

其他防护：工作现场禁止吸烟、进食和饮水。工作完毕，淋浴更衣。保持良好的卫生习惯。

Other protections: Smoking, eating, and drinking are prohibited at the workplace. After work, take a shower and change clothes. Maintain good hygiene habits.
