Scientists at Allahabad University have developed a device to remove heavy toxic metal ions from water. This new device can prove to be helpful in making access to clean water easier for people. The device is made from carbon nano tube membranes in a capsule model. Its patent is for ten years.
Dean Science in the Department of Chemistry of the University, Prof. Research student Rahul Kanojia has created this unique device under the guidance of Shekhar Srivastava. Rahul told that the device of capsule-like structure made of carbon nanotube membranes has been prepared.
This nanotechnology based device will clean the contaminants, turbidity, oil, bacteria, viruses from water.The Kolkata-based Controller Journal of Patent Design and Denmark, Ministry of Commerce and Industry, Government of India, has recognized this design for a period of 10 years. The patent is published in the Official Patent Gazetteer General of the Government of India.
Rahul told that Dr. Yashwant Rao of Jharkhand, Dr. Pandurang of Maharashtra, Dr. J Madhusudan of Tamil Nadu, Dr. Aruna Kumari of Andhra Pradesh etc. were involved in this discovery.Thoughts on attaching molecules to nanocarbons
To improve adsorption, scientists are looking at attaching molecules to nanocarbons. Scientists are also trying to find ways to use all available surfaces for metal ion adsorption. This will increase their ability to adsorb more metal ions at a time.
