- The Ministry of Science & Technology has developed a newly developed composite membrane made from two or more materials called Mixed Matrix Membrane (MMM).
- It will help in the detection of ammonia or other amine leaks in laboratories or industrial settings.
- Ammonia and other aliphatic amines are hazardous for human beings. They are used as raw materials for chemical, fertilizer, and food industries.
- They are highly toxic and corrosive and become dispersed in the environment.
- The detection of ammonia is essential for effective environmental and water monitoring.
- It is extremely important for preventing onsite gas leakage and disasters.
- The researchers used these to fabricate a mixed matrix membrane of MOF nanosheet that showed a naked-eye colour change in the presence of NH3 and aliphatic amines.
- The MMM showed fabricated remarkable colour change when exposed to vapours of different amines.
