UARM Effective Route for Cu- and Zn- MOFs as Highly Efficient Adsorbents Towards Arsine (AsH3) Gas Adsorption: Design and a Systematic Study

Abstract

Since it is essential to select the adsorbents, which are prepared with fast, environmentally friendly, and affordable methods, therefore, in this study, the Cu- and Zn- metal organic framework nanostructures were synthesized in the shortest route with the high efficiency by the effective method of ultrasonic assisted inverse micelle (UAIM) method. The synthesized samples were used as the new adsorbents in the arsine gas adsorption. The physicochemical properties of the products were examined in detail, so that the adsorbent dosage, temperature and pressure for the preparation of samples with distinctive characteristics were 0.05 mg, 25.00 °C, and 5.00 bar, respectively. Since the design and control of experimental parameters to find the best conditions for producing the samples with high adsorption efficiency is essential in this process, thus, for this purpose, fractional factorial design and response surface methodology were used. The results indicated the high efficiency of arsine gas adsorption for the synthesized samples in optimized conditions. The differences between arsine gas adsorption in this study in comparison with the previous studies could be due to the characteristic’s improvement using the effective synthetic methods as well as the systematic study of experimental parameters.
