INVESTIGATION OF CO GAS CAPTURING BY ROOM 2 TEMPERATURE IONIC LIQUIDS

       Some  ionic liquids were investigated for abilities to capture COalone or with added some catalysts at room temperature under atmospheric pressure to increase the capacity of ionic liquids  to capture
carbon dioxide gas  some catalysts were found effective such as :- Hydrated aluminum nitrate/urea ionic liquid  with added CaO  and n NaOH , monoethanolamine and  ammonium chloride were added to
hydrated ammonium aluminum sulphate/urea ionic liquid did not show in FTIR sign of either physical or chemical absorption of CO2  The addition of  NaOHaq to hydrated  ammonium  aluminum sulphate/urea ionic liquid  showed a new vibration absorption  at 1666cm-1  and changing  the  frequencies in the amine group vibrational  bands  above 3000 cm-1 While the distilled water when added to the ionic
liquid hydrated ammonium aluminum sulphate/urea  showed a broaden effect on  the high  vibrational bands above 2500 cm-1 and the carbonyl group vibrational  band at 1662 cm-1 was not effected           Calcium oxide was added to hydrated ammonium aluminum sulphate/urea showed a new  splitting  vibration  absorption bands at 1666 cm-1 ,1618 cm-1                                                                                       
          Aluminum chloride-urea ionic liquid very effective to capture carbon dioxide gas without add any catalysts showed a chemical absorption of CO2
 1655 cm1  while aluminum chloride-acetamide showed weaker or no  ability to capture CO2
