Preparation and characterization of 5-sulphosalicylic acid doped tetraethoxysilane composite ion-exchange material by sol-gel method

- Sulphosalicylic acid doped tetraethoxysilane composite is prepared by sol-gel method.
- Its X-ray diffraction studies suggest that it is crystalline in nature.
- This material shows selectivity for Mg(II) and Ni(II) ions in aqueous solutions.
- Separation of Ni(II) from binary mixtures was successfully achieved on this material.
