Multifunctional and regenerable N-chlorine based biocidal and detoxifying metal-organic frameworks are provided. Chloramine functional groups on the organic linkers of the metal-organic frameworks act as chlorine carriers. Pathogens or harmful organic compounds that come into contact with the metal-organic frameworks in the presence of water are rendered inactive by reactions with the active chlorine. The metal-organic frameworks can be incorporated into textiles used to make protective wearable articles.
