Recovery of rare earth from waste water

Rare earth elements are essential for making modern electronic devices such as magnets, catalysts, superconductors . But because they are rare, they are very expensive. But recently scientists have found a way to recover rare earths from industrial wastewater .

Researchers from the Chinese Academy of Sciences found a nanomaterial called nano-Mg (OH) ₂ that could help remove some metals and dyes from wastewater.

This substance can also help to recover rare earths which are very thin in industrial wastewater, with much cheaper prices than exploiting rare earths from underground.

The study of nano-Mg (OH) ₂ shows that they can be produced in the form of special flowers. Experimental laboratory simulations show that these particles are capable of capturing 85% of rare earth that has been diluted diluted in water samples. Then adjust the pH to separate the rare earth element from nano-Mg (OH) ₂ .

Gizmag magazine quoted the research team as saying that recycling of rare earth elements from waste water not only saves resources, contributes to environmental protection but also brings significant economic benefits.
