Water Filtration Methods with Activated Charcoal

WebThere are two approaches for preparing activated carbon that can be used in water purification processes: physical activation and chemical activation. Activated carbon has good potential for adsorbing heavy metals because of its greater surface area, microporous ability, and chemical complexity of its external area. WebThe adsorbed material is held physically, rather loosely, and can be released (desorbed) rather easily by either heat or vacuum. By contrast, an absorber reacts chemically with the substance being absorbed, and thus holds the absorbed substance much more strongly, requiring much more energy to release the absorbed substance. read it out loud text free
