| My name is Ossama Mahmoud, I am in grade 9 and go to the Al-taqwa Islamic School. I really enjoy science and math. I got inspired to do this project because I wanted to find out how clean the water is in London, especially that one of the biggest water polutants are heavy metals. I did some research and found out that I can use certain types of plants to clean water. My favorite sport is Judo, I am a blue belt and enjoy competing at high levels. This is my second year in the Canada wide science fair. In the future I would like to be a physician. |

The use of Ca-alginate beads to remove heavy metal contamination from water
| Défi: | Environnement | | Catégorie: | Intermédiaire | | Région: | London District | | Ville: | London, ON | | École: | Al Taqwa Islamic Secondary School | | Sommaire: | In this project, I tested the potential of an affordable readily available material (Ca-alginate beads) to remove heavy metals (using a multi-element solution and a single element solution of Pb) from our water systems. The Ca-alginate beads were able to remove all the heavy metals from the water at different degrees. Also, a prototype filter using the Ca-alginate beads was constructed and successfully tested. |
