The Effects Of The Dissolution Of Ni And Co)

The overlying questions asked in this experiment were: does the dissolution of metal ions (Ni and Co) from NMC particles into solution change over time as well as to how small particles (glucose) affect this dissolution. From the wet chemistry Figure 3b, it can be seen that the concentration of Co appears to begin and remain between 7 and 10 μM, meaning that the majority of dissolution takes place immediately when the solution is constructed, then increases at a slow rate onwards. This does not appear to hold true for Ni (Figure 3a; rather the concentration consistently began under 0.5 μM but rose to rear or above 5 μM in each case. From this, it was determined that the dissolution of Ni and Co do not require the same amount of time to initiate, rather, that Co …show more content…
The inconclusiveness of results indicates that more research needs to be done to fully understand dissolution. The slight possibility hinted at by ICP data that glucose could be a promoter provides a reason for further research. Since glucose is a common sugar found in plants, animals, and food, it is possible that NMC in the environment could come into contact with glucose. If glucose is a promoter, then this makes loose NMC potentially more environmentally harmful. When investigating the dissolution of NMC, it is important to use precise methods as small concentrations of transition metals are commonplace. With current data, the hypothesis that glucose inhibits the dissolution of Ni is not supported. However, the research points in directions for future studies, as ICP data hints that glucose might be a promoter. Future studies need refined accuracy, more frequent measurements, and an increased range of glucose concentrations. Continued research on the dissolution of NMC under varying conditions is needed to fully understand the impact of one’s
