separation process molybdenum

2/N 2 separation is a pressure driven process, where the driving force is induced by the difference in pressure between downstream and upstream sides. The membrane used in the gas separation process is generally non-porous layer, so there will be no severe leakage of gas across the membrane due to the membrane porosity [7].

Molybdenum is frequently associated with tungsten in mineral deposits, and their chemical properties are quite similar. Therefore, for many years, removal of impurity molybdenum from tungsten has been a worldwide technical problem. In this work, a separation process was investigated with the use of copper-bearing materials as the scavenging agents.

In this study, we examine the role of the lamellar structure of 2D membranes on their performance. Using self-fabricated molybdenum disulfide (MoS2) membranes as a platform, we show that the separation layer of 2D nanosheet frameworks not only fails to demonstrate water-salt selectivity but also exhibits low rejection toward dye molecules.
