A group of researchers created a method that could create drinking water in a mere 30 minutes.
on a planet whose surface is 71% water? Hopefully, that's one of those surprising general trivia questions that future generations will ask themselves.able to transform brackish water and seawater into safe, clean drinking water in less than 30 minutes using metal-organic frameworks and sunlight.MOFs are incredibly porous materials with very high surface areas — they
consist of metal ions that form a crystalline material with the largest surface area of any material known. In this case, the team of researchers developed a completely new MOF, dubbed PSP-MIL-53, which is able to trap impurities and salt from seawater and dirty water. Essentially, when the material is placed in the water, it pulls the ions out of the liquid and holds them on its surface. , the research team showed that, using their MOF, they were able to reduce the total dissolved solids in the water from 2,233 parts per million to under 500 ppm.
The problem is that thermal desalination processes that rely on evaporation typically require high energy consumption. Other methods, such as reverse osmosis are also highly energy-intensive and require a lot of chemicals for cleaning and dechlorination. “Sunlight is the most abundant and renewable source of energy on Earth.," Professor Wang explains."Our development of a new adsorbent-based
