近年来,人们发现铝离子对于人体健康和水系统的有害影响不断增加,但是铝盐在饮用水处理中是应用最为广泛的无机盐类混凝剂,处理不到位时将导致饮用水中铝含量的增加。目前,水厂普遍使用硫酸铝或聚合氯化铝作为混凝剂。我们在实验室日常检测过程中发现,当使用硫酸铝作混凝剂时,用铬天青S分光光度法能准确地测定出饮用水中的铝含量,而使用聚合氯
In recent years, it has been found that aluminum ions have a detrimental effect on human health and water systems. However, aluminum salts are the most widely used inorganic salt coagulants in drinking water treatment. When not in place, aluminum salts will cause the content of aluminum in drinking water Increase. Currently, water plants commonly use aluminum sulfate or polyaluminum chloride as a coagulant. Our routine tests in the laboratory found that when using aluminum sulfate as a coagulant, chromium Azurol S spectrophotometry can accurately determine the aluminum content of drinking water, and the use of polymeric chlorine
