Preparation method and application of functionalized active nano-porous carbon

Abstract

The present disclosure relates to a simple method for purifying drinking water using a pouch or a filter device connectable to a faucet, the pouch or filter device comprising powdered or particulate hydroxyl and phosphate functionalized active nanoporous carbon derived from waste coco coir. The suggested coconut coir steam treatment method can endow the coconut fiber with hydroxyl and phosphate functional groups, and pyrolysis in an inert environment can form a nano-porous carbon network. The active nano-porous carbon can be used for removing hard substances, fluorides and heavy metals existing in drinking water. The material is loaded into a membrane filter (a pouch like a tea bag) or into a post connectable to a domestic faucet.
