| Abstract: | Titanium-hydroxyethylidene diphosphonate (TiHEDP), a novel hybrid ion exchange material of the class of tetravalent
metal acid (tma) salt, has been synthesized by sol-gel method and characterized by elemental analysis (ICP-AES), thermal
analysis (TG / DTA and DSC), FT-IR and X-ray diffraction studies. Chemical resistivity of the material in acids, bases and
organic solvents has been assessed. Sorption behaviour of dyes, crystal violet (CV), rhodamine 6G (R6G), methylene blue
(MB) and pink FG (PFG) towards TiHEDP has been studied, based on thermodynamic parameters evaluated and adsorption
isotherms (Langmuir and Fruendlich). Breakthrough capacity and elution behaviour of dyes have also been studied. Sorption
affinity of dyes towards TiHEDP is found to be MB>CV>R6G>PFG. |
