Super Absorbent Cotton – Innovation of BARC

 

Water pollution due to the oil spilling accidents has brought up many environmental and even ecological troubles. These troubles can be one of the measure threats to human health all over the world. Indian scientists have found the solution for one of the measure oil pollution dilemma. The issue for which developed countries like Russia and the united nation were in big trouble. Super Absorbent Cotton can be the solution to oil pollution.

Super Absorbent Cotton- solution to oil pollution

Bharat Atomic Research Center ( situated in India) is the leading multi-disciplinary nuclear research center of the government of India. Scientist Dr. Subhendu Ray Chowdhary is the man Of innovation. He developed this super-absorbent cotton material by applying radiation technology. Currently, he is working in the Isotopes and radiation application division. He received the national award for technology innovation 2019 by the Ministry of Chemicals and fertilizers by govt of India for the innovation of super-absorbent cotton.

The super absorbent cotton has a multifunctional ability to separate the hydrocarbon-based solvent or halo hydrocarbon and low surface energy liquid from aqueous media. This cotton is a highly efficient material with superhydrophobic and super oleophilic properties. The super-absorbent material is developed by radiation technology.

No other country has developed such material to date that can remove oil from the surface of water and sediment oil simultaneously, says Director of BARC dr. A.K Mohanty.

We heard many times about the oil spilling incidents in oceans which ended up getting spread all over the oceans which can not fully recover by traditional methods. It either burns it away by controlled burning method or by cutting the oil molecules into micro particles for consumption by the microorganism, but oil does not fully recover in both ways. And for such oil spilling. This super-absorbent cotton material is the antidote. Super-absorbent cotton is the best method to recover spilled oil from oceans.

This super-absorbent material can collect the leaking oil from oceans. Separate the harmful industrial chemicals or laboratory setup and spillage road. The 1 Kg of that cotton material can absorb a minimum of 1.5 kg oil, which can simply recollect by compression from super cotton or by squeezing the sheet. The promising feature of this super material is biodegradability. As a result of which the use of this application will not affect the environment as well as marine life.

This eco-friendly material can use multiple times to collect the oil from water, i.e. up to 50-100 times before throwing it.

The statement by BARC said, The fabric was developed by bio-inspired molecular-scale surface engineering through turning of surface roughness, and surface energy with the assistance of radiation assisted covalent integration.

Super-absorbent cotton is the best innovation to control oil pollution. Super absorbent cotton is beneficial for removing toxic liquids like toluene, Benzen, Ethylbenzene, TBP, TPP, Chloroform, and Dichloromethane from industrial waste.
The conventional methods for oil removal create secondary pollutants and lose oil due to burning or sometimes due to consumption by microorganisms. However, this new technique is cost-effective and can recover most of the oil, ultimately adding value to the economy.

Properties of  Super Cotton

  1. ability to separate the hydrocarbon-based solvent or halo hydrocarbon and low surface energy liquid from aqueous media.
  2. The 1 Kg of that cotton material can absorb a minimum of 1.5 kg of oil.
  3. It is beneficial for removing toxic liquids.
  4. This eco-friendly material can use multiple times like 50-100 times to collect the oil from Aqueous media.

 

This material can also be used for separating industrial oil solvents and cleaning solid surfaces in oil stations. This super-absorbent cotton can conserve its property for a long time. And even does not get affected by either acidic or alkaline nor by high-temperature situations.

As a consequence success of this project, the production of super absorbent cotton has been expanded in large quantities. Because of its flexible design and weather resistance properties, the material can be stored for a more extended period as per the requirements.
In December 2020, an Indian patent was granted on this unique super absorbent material. This technology has been transferred to a private company manufactured in India for other countries.
