The best indicator was ICP, which was the most accurate method used to measure Ni concentration. The main trend to be taken away from this data is that all vessels containing glucose, when compared time point to time point, release more Ni at every stage that does the experimental control, which contains no glucose. These differences are small. For example, at 62.5 hours, the control has released 0.055 mg/L of Ni. Vial 2 and Vial 5 have released 0.075 and 0.070 mg/L Ni respectively. The Vial 2 and 5 concentrations are very similar; however the control has a concentration slightly more significantly different, 0.015 mg/L away from Vial 5’s concentration. This data is not enough to make any conclusive statements. However, this trend is enough to give reason for more research. If the same results are reproduced in triplicate, this would provide evidence that glucose could promote the dissociation of …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
