Dhaka University (DU) scientist Dr. Abul Khair has discovered 'Law of Electrolytic Diffusion' which will help open a new era in the science arena. Besides, the scientist also invented a glass diffusion tube named 'Reaction Diffuser which they used to carry out this unique research.

"Following the discovery of 'Law of Electrolytic Diffusion' science specially chemistry has entered into a new era. The instrument and the law will come in exceptional use of Chemistry and the Allied Sciences, Hydrogeology and the Medical Engineering," Professor Dr Abul Khair told The Independent. A group of researchers led by Professor Dr Abul Khair of Dhaka University (DU) `worked hard for 15 years to discover the "Law of Electrolytic Diffusion".

Abul Khair, Prof of chemistry department of the university said that the law states that the velocity of diffusion of an electrolyte in water is directly proportional to the square root of its molar mass. Terming the law as universal he said, " That the heavier electrolyte travels faster." He said that the law would be used to enrich uranium. Abul Khair invented a glass diffusion tube in 1995 namely "Reaction Diffuser'.

Dr GM Golzar Hossain, assistant Prof of the department, M Saiful Alam, chairman of Applied Chemistry and Chemical Technology Department of Noakhali Science and Technology University were the members of the research group. He said that the Bangladesh Patent office recently registered both the invention and discovery. He said that there will be an unprecedented demand of the Reaction Diffuser all over the world.

Remarking that chemistry enters into a new era of development, he said, "Osmosis and kidney dialysis will receive new look keeping the law in view." The Reaction Diffuser will be used in chemistry to study the periodicity of elements, to determine the molar masses of salts, their concentrations in solutions and their purity, he said adding that salts in crystalline form will be prepared using diffusion controlled reactions. Prof Khair said that in 1831 the law was discovered by Thomas Graham for diffusion of gases in air but supports those of Adolf Fick discovered in 1855 for diffusion of solutes in water; he said the new law is completely different from these.
