Objective:
Our objective is to use bismuth nanoparticles to detect lead ions within drinking water using visual detection methods. We will also investigate if it is possible to use bismuth nanoparticles in a similar manner to how gold nanoparticles are used.
Approach:
This research would focus on using bismuth nanoparticles to detect lead ions within water. We would do this by mixing multiple different functional nanoparticles and microparticles to form bonds with lead ions. Our intent is to help individuals detect lead where heavy metal contamination is a problem.
Expected Results:
This is an intermediate study to further understand the use of bismuth nanoparticles in lead detection. Potential results include a definite color change of the solution if lead is present. Bismuth has characteristics that warrant trials of this procedure as further understanding of bismuth nanoparticles is necessary. If bismuth is found to not perform in this procedure, it provides researchers with a new understanding, and they are able to move in a different direction in replacing gold nanoparticles. On the other hand, success would demonstrate that bismuth can be used in place of gold in the given lead detection procedure. The ability to use bismuth makes the procedure more affordable and therefore potentially more accessible to communities in need.
