摘    要:作为洗涤剂助剂,沸石的主要作用是通过离子交换降低水中的钙镁离子浓度、软化洗涤用水以提高洗涤剂中的表面活性剂的洗涤效率。因此,沸石对钙镁离子交换容量的大小和交换速率的快慢是评价洗涤用沸石的重要质量指标[1,2]。目前,使用最多的沸石类助剂为NaA沸石。为了弥补NaA型沸石镁离子交换能力的不足,先后又出现了A、X型沸石混合使用[3]、高铝X型沸石(MAX)[4~5]和高铝P型沸石(MAP)等技术[1,2]。MAX型和MAP型沸石与NaA型沸石一样具有最小的硅铝比(SiO2/Al2O3=2)。因此,这三种沸石的…

关 键 词:沸石  钙离子交换  交换性能  洗涤剂助剂

Abstract:Calcium ion exchange behavior of Zeolites used in detergent such as NaA, NaX and NaP was studied by Ion Selective Electrode Method (ISE). The linear relationship between calcium ion exchange capacity and framework aluminum content of zeolite NaX was found, and the effects of exchange temperature, concentration of zeolite and other cations on calcium ion exchange behavior were also investigated. The sequence of the calcium ion exchange selectivity of zeolite MAP, NaA and NaP was determined. The framework structure of zeolite NaA, NaX and NaP significantly influence the cation exchange behavior of these three zeolites.
Keywords:detergent    zeolites  calcium ion  exchange
