MOFs were reported for treating water. MOFs, a unique class of porous materials, have drawn a lot of interest in the past 10 years due to their enormous promise in a wide range of applications. High surface area, high porosity, and chemical and thermal stability are typical features of MOFs. It has been reported that MOFs have been investigated for the removal of heavy metal ions from aqueous solutions. The necessity for a filter or centrifuge to extract MOFs following the adsorption process makes large-scale application of MOFs still difficult.
