Most of the hazards risk in workshops and hobby rooms come from the use of highly dangerous chemical solutions called solvents. A solvent is a substance designed primarily to dissolve other substances — paint strippers or stain removers, for example. Solvents containing carbon are known as organic solvents and are both flammable and toxic. When used, stored or disposed of incorrectly, organic solvents can cause environmental problems such as air pollution, water and soil contamination, as well as being harmful to wildlife. In addition to the risks of fire and poisoning, solvents can also cause skin damage, eye injury, allergies, nervous system disorders, and nerve, lung, liver and kidney damage. Extraction is most versatile and widely used method for the removal of pollutants due its high removal capacity. The only disadvantage of extraction method is that it‘s giving harmful impact on the environment and also human health. Ionic liquid as a greener solvent had been chose as an extracting agent for this process to make this method the most benefit and environmentally friendly compared to other methods. The main objective of the project is to study the potential of bmim thiocyanate as extraction agent for calcium from organic solvent. There are two parameters that being studied for extraction which are the concentration of calcium ion in dodecane and the temperature for extraction. 20ppm,30ppm,40ppm and 50ppm of calcium being extracted from dodecane using Bmim Thiocyanate. The samples being extracted in three differents temperature which is 25°C, 35°C and 45°C. The research shows that as the temperature and concentration of calcium in dodecane is increase, the extraction percentages increase as well.
