Research progress on the adsorption of heavy metal ions in water by metal-organic frameworks materials
Describing the common MOF materials with water stability and the progress of research on the modification of MOF materials to improve the adsorption capacity of heavy metal ions in water.It is point-ed out that the functional group grafting modification and the preparation of MOF-based composites are crucial in improving the adsorption capacity of MOF materials for heavy metal ions in water.The prepara-tion and modification of MOF materials for the removal of heavy metal ions in water is promising,but there are problems of high preparation cost and insufficient long-term operational stability that need to be solved for the application of MOF materials as adsorbents for water treatment,and there is still a long way to go for the engineering application of MOF materials.The engineering application of MOF materials still has a long way to go.
