性能概述
过硫酸钠是一种白色无味晶体、或粉末，被乙醇分解，常温时稳定性好。常作强氧化剂使用，也可用作单体聚合引发剂。它几乎不吸潮，便于储存，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.

储存及使用注意事项：
过硫酸钠属于非易燃品，但由于能释放氧而有助燃作用，因此必须在一定条件下储存。首先必须存放在干燥、密闭的容器中，其次应避免阳光直射、热源、潮湿等不利因素。另外，一些杂质如脏物、铁锈、少量金属以及还原剂可能引起过硫酸钠的分解，在存放和使用过程中也必须注意。由于潮湿的过硫酸钠粉末及其水溶液有漂白和轻微的腐蚀作用，因此使用过程中应避免眼睛、皮肤和衣物直接与其接触。
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.
