DEVELOPMENT OF METAL – ORGANIC FRAMEWORKS, SURFACE ABSORBENT OF BILOGICAL POLLUTANTS, INCLUDING HEAVY METALS
Maqola haqida umumiy ma'lumotlar
The global level of environmental pollution with metals has increased greatly in the last two centuries. The presence of some heavy metals in aquatic ecosystems is a constant threat to the health of human societies. Many of these metals, such as chromium (Cr), copper (Cu)), iron (Fe) and cobalt (Co) are essential for plants, living organisms and the human body. While large amounts of these metals are toxic and dangerous for living cells. Porous coordination polymers or metal-organic frameworks (MOFs) are a new class of crystalline and microporous materials that include inorganic secondary structural units connected by organic parts in the form of three-dimensional arrays through coordination bonds. Evaluation of the relationship between the structure and performance of metal-organic frameworks is an interesting topic discussed in this work. The metal-organic framework, {[Zn2(OH)(AZPY)(BDC)1.5].H2O}n was successfully chemically saturated. The surface adsorption efficiency of the considered framework for some heavy metal ions was investigated in order to investigate the effect of the type of functional groups in different pillars in the adsorption process. The results showed that the framework with the Omid factor group showed a better result.
