性能概述
過硫酸鈉是一種白色無味晶體、或粉末，被乙醇分解，常溫時穩定性好。常作強氧化劑使用，也可用作單體聚合引發劑。它幾乎不吸潮，便于儲存，使用方便，安全。
Description
Sodium persulfate is a white, crystalline, odourless salt. It is used as initiator for the Polymerization of monomers and as a strong oxidizing agent in many applications. It has the particular advantage of being almost non-hygroscopic, of having particularly good storage stability as a result of its extremely high purity and of being easy and safe to handle.

儲存及使用注意事項：
過硫酸鈉屬于非易燃品，但由于能釋放氧而有助燃作用，因此必須在一定條件下儲存。首先必須存放在干燥、密閉的容器中，其次應避免陽光直射、熱源、潮濕等不利因素。另外，一些雜質如臟物、鐵銹、少量金屬以及還原劑可能引起過硫酸鈉的分解，在存放和使用過程中也必須注意。由于潮濕的過硫酸鈉粉末及其水溶液有漂白和輕微的腐蝕作用，因此使用過程中應避免眼睛、皮膚和衣物直接與其接觸。
Precautions during Storage and Use:
Sodium persulfate is a kind of non-inflammable product, but it has combustion-supporting action because it can release oxygen, therefore, it should be stored under certain conditions. First, it should be stored in dry and closed container; Second, it should keep away from sunlight, heat sources and moisture; Moreover, some impurities such as defilement, rust, some metals and reducers can cause the decomposition of ammonium persulfate, therefore, these matters should be paid attention to during storage and use. Because the moist ammonium persulfate powder and its aqueous solution have bleaching and slight corrosiveness, the operate should avoid eyes, skins or clothing direct contacting with it.
