Abstract
The zeolites are a popular group of minerals known as hydrous aluminumsilicate. More than forty naturally occurring zeolites were reported by different research groups and more than 150 zeolites have been synthesized. They have been increasingly used in various application areas such as industry, agriculture, and environmental protection. This research paper reviews the recent patents of using zeolites in environment, agriculture and pharmaceuticals. Agriculture has more concern in the last ten years in the world, so zeolites can be used as agricultural and horticultural fungicide and as soil amendment. The use of zeolites in water treatment is an important environmental application. The first application in water purification by adding zeolite crystalloid coagulant ("ZCC") to water that contains particulate matter that has multivalent ions adsorbed on the surfaces thereof. Other application is a process for the treatment of contaminated water based on the use of zeolites having different characteristics. Utilization of zeolites for treatment of contaminated water under different conditions in environmental applications is also discussed. The review also carries the recent patents available in water treatment process, agricultural and pharmaceutical industry.
Keywords: Zeolites, Agriculture, Environment, Fungicide, Water treatment, Pharmaceutical industry.
