In this research, nanostructures were synthesized and their ability to eliminate dye pollutants was investigated. Metal Organic Frameworks (MOFs) are a new type of materials that have numerous applications in many aspects due to their high structural-dependent potentials, including gas storage and separation ability, ion exchanging, catalytic activity and drug delivery. These materials have recently been used in the elimination of hazardous materials as sorbents due to the presence of regular and homogenous canals and pores at nanometric scale.

The researchers produced porous metal organic frameworks in this research for the elimination of Congo red that is found in industrial wastewaters, specially in textile industry. Congo red is a synthetic and toxic dye, which causes cancer in humans. The dye is soluble in water and creates a red colloid solution.

The industrial production of frameworks is possible due to the simplicity of the synthesis process. Application of the product or the similar improved samples enables the purification of industrial wastewaters. In addition, the product decreases environmental pollution due to the sorption of high amounts of pollutants in a short period of time.

The researchers have synthesized two new frameworks entitled TMU-8 and TMU-9 to produce the sorbent from cadmium and organic ligands.
