目前，4A沸石被认为是洗涤剂助剂三聚磷酸钠的优良代用品，国外已工业化生产，国内各地也都积极开发。为了控制产品质量、统一分析方法，轻工业部日用化学工业科学研究所自1982年4月接受了轻工业部下达的4A沸石分析方法的研究，经过三年完成了4A沸石的钙离子交换能力、粒度和平均粒径、白度、pH值、水份等分析方法的研究，提出了各分析方法，并于1985年6月通过技术鉴定。现将前两个方法摘要刊出。
At present, zeolite 4A is considered as an excellent substitute of sodium tripolyphosphate detergent additive. It has been industrially produced abroad and has been actively developed throughout China. In order to control product quality and unify the analytical methods, the Institute of Daily Chemical Industry, Ministry of Light Industry, has accepted the study of 4A zeolite analysis method issued by the Ministry of Light Industry since April 1982 and completed the calcium ion exchange capacity of 4A zeolite after three years. The particle size And the average particle size, whiteness, pH, moisture and other analytical methods, put forward various analytical methods, and in June 1985 passed the technical appraisal. The first two methods are now summarized.
