The use of atmospheric water as a source of fresh water is still underdeveloped due to lack of innovative desiccant materials. Yet, the collection of water from the air and contain it is a promising way to supply fresh water for consumption or irrigation in remote, hot, arid regions. The collection process requires porous materials such as zeolites and/or hygroscopic (desiccant) salts such as sodium and potassium carboxylate salts. The collected water can be released through evaporation at 100 °C. Current atmospheric water-harvesting technologies rely on corrosive salts such as calcium chloride, lithium chloride, lithium bromide, sodium chloride, lye, potassium chloride, potassium hydroxide, etc. The availability of alternative, less corrosive, sodium and potassium carboxylate desiccants equip water harvesters with more user-friendly materials. In addition, leading researchers have established that the carboxylate salts can be coupled with traditional zeolites, polymer composites, and other porous metal-organic framework materials. Leading scientists such as Dr. Omar Yaghi of Massachusetts Institute of Technology and the University of California Berkeley have published very interesting pioneering work in the water-harvesting arena.
