Ions of metals
WebObjective: To investigate the effect of oxidized transitional metal (ferric and cupric) ions on the amino acids. Methods: 25 mmol/L hydroxyproline and 25 mmol/L histidine were incubated with 50 μL Fe 3+ and Cu 2+ ions at pH 7.4 and 37 °C for 30 mins in separate test tubes. Then 500 μL of 1% thiobarbituricacid (TBA) was added to the incubated amino … WebI'll get aluminum cans and vape pens. The vape pens casings seem to be made of a soft metal, probably aluminum, but most all of them have been run over already. If they haven't been ran over then the lithium ion cells can be repurposed, the crushed ones will need to be opened, cleaned and sorted.
