| Résumé : |
The toxic effects of mercury and other heavy metals present in the environment are well known and thus many efforts are being put forward to reduce their levels. One such technology that has come up involves using a material, Sulphur Limonene Polysulphide (SLP) which has the capacity to reduce the metal content upto 55%. It is a polymer that is prepared using sulphur and limonene which are the by products of oil refinery and citric juice industries respectively. This makes the technology comparatively of a lower cost, and also easy to commercialize based on the abundance of the raw materials required. The polymer synthesized can be used as a coating or a solid device that adsorbs the heavy metals from its surroundings, which further penetrates inside the surface of polysulphide, likely due to its malleable nature and high density of mercury. Another distinct feature of this polymer is that it changes colour from red to yellow as it adsorbs mercury, which gives a qualitative idea of when the device is saturated and needs to be replaced. Also a study was done which showed that SLP does not release any harmful materials into the environment, thus making it an efficient and commercial technology to extract the toxic metals in the environment. |
