摘要：NOVELTY - Slow release chelating agent comprises sustained-release carrier and drug. The sustained-release carrier is environment-friendly and biodegradable material, preferably chitosan or chitosan derivative. The drug is chelating agent. USE - Slow release chelating agent used for phytoremediating soil (claimed). ADVANTAGE - The slow release chelating agent reduces agent release rate in water and avoids slow-release carrier that cannot degraded in soil during process causing secondary pollution. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of slow release chelating agent comprising dissolving chelating agent in water, adding to sustained-release carrier, mixing and spray drying.
