Heterogeneous membranes

1 - 2 of 2 results

Spontaneous reduction of 4-nitrobenzene diazonium salt on coal in acetonitrile or HCl aqueous solution permits the strong bonding of aryl groups to its surface as shown by IR spectroscopy. Heterogeneous reverse osmosis membranes containing small particles of coal modified with aryldiazonium salts we

As the preparation of interpolyme- type anion-exchange membranes involves several steps and the use of hazardous chemicals such as chloromethyl ether and trimethyl amine, it was envisaged to prepare heterogeneous anion-exchange membranes through a simple technique involving casting of a solution con
