Abstract:

Metal Organic Frameworks (MOFs) have attracted great interest in recent years, taking a leader role in the field of catalysis, drug delivery, sensors and adsorption.[1] In the past decade, promising results have been reported specifically in the field of adsorption, based on the topology and chemical features of this type of porous materials.[2] Thus, their application in industry and environment for the adsorption of pollutants is presented as a reponse to an increasingly important need.

In this area, organic dyes are nowadays widely used in many industries including medicine, textile, leather, printing and plastics.[3] As a consequence, dyes are present as emerging pollutants in soils and water where they remain for long periods of time due to their stability, with a potential risk of toxicity in wildlife and in humans. On the other hand, the presence of iodine in soils, water and gas as a nuclear activity pollutant product or its extended use as a germicide is still a problem in many countries, which indicates the imperative need for its removal.

In this context, this work presents the caracterization as an adsorbent of the activated compound MOP@Ei2-1,[4] Which consist of cuboctahedric nanoballs of 24 CuII atoms arranged in 12 paddle-wheels, linked by 1,3-benzenedicarboxylic acid ligand (m-BDC). Adsorption of dyes and iodine as pollutant examples has been carried out focusing attention on the kinetics of the rapid process.
