過硫酸鉀存放時間：過硫酸鉀作為氧化劑，應避免與還原性物質、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.
過硫酸鉀溶液更不能長期存放，標準中規(guī)定堿性過硫酸鉀溶液在聚乙烯瓶中存放不能超過 7 d。堿性過硫酸鉀在27～30 ℃ 環(huán)境下，存放超過3 d，空白值就會大于0. 030 建議實驗時盡量根據近 3 d 的需求量配制，存放盡量不要超過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.
過硫酸鉀溶液存放條件
Storage conditions of Potassium persulfate solution
儲存注意事項：儲存于陰涼、干燥、通風良好的庫房。遠離火種、熱源。包裝密封。應與還原劑、活性金屬粉末、堿類、醇類等分開存放，切忌混儲。
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.
過硫酸鉀溶液保質期：一周。過硫酸鉀具有強氧化性，不穩(wěn)定，易分解，放出氧變?yōu)榻沽蛩徕洠?00℃時完全分解，其溶液長期貯存濃度會改變。
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.
抗壞血酸溶液保質期：兩周。由于抗壞血酸溶液易被氧化，通常加抗氧化劑如PVP，巰基乙醇等能維持穩(wěn)定抗壞血酸溶液喜酸怕堿，高溫和強光下會被氧化，所以盡量低溫使用不透光的瓶子保存通常冷藏避光條件下，存放時間不宜超過半年。
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.
監(jiān)測方法
Monitoring methods
工程控制：過程密閉，加強通風。提供淋浴和洗眼設備。
Engineering control: The production process is sealed and ventilation is strengthened. Provide safety showers and eye wash equipment.
呼吸系統(tǒng)防護：可能接觸其粉塵時，應該佩戴頭罩型電動送風過濾式防塵呼吸器。高濃度環(huán)境中，建議佩戴自給式呼吸器。
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.
眼睛防護：呼吸系統(tǒng)防護中已作防護。
Eye protection: Protective measures have been taken in respiratory system protection.
身體防護：穿聚乙烯防毒服。
Body protection: Wear polyethylene protective clothing.
手防護：戴橡膠手套。
Hand protection: Wear rubber gloves.
其他防護：工作現場禁止吸煙、進食和飲水。工作完畢，淋浴更衣。保持良好的衛(wèi)生習慣。
Other protections: Smoking, eating, and drinking are prohibited at the workplace. After work, take a shower and change clothes. Maintain good hygiene habits.
