Metal organic resins, composite materials composed of the metal organic resins, and anion exchange columns packed with the composite materials are provided. Also provided are methods of using the composite materials to remove metal anions from a sample, methods of using the metal organic resins as fluorescence sensors for detecting metal anions in a sample, and methods of making the metal organic resins and the composite materials. The metal organic resins are amine-functionalized metal organic frameworks and their associated counter anions. The composite materials are composed of metal organic resin particles coated with organic polymers, such as alginic acid polymers.
