Task 3 was to design and test a series of superabsorbent pillows to identify a quantitative trend that can efficiently clean-up spills of heavy metal ion solutions. This investigation has value to companies or people they want to find a way to efficiently clean-up spills of toxic metals in bodies of waters that could damage species in and around these waters.
Experimental Design and Procedure In order to efficiently clean-up spills of heavy metal ion solutions, we implemented an experimental design by having the amount of sodium polyacrylate inside our superabsorbent pillow be our independent variable. We chose this variable as our treatments because the goal of our experiment was to test how the amount of …show more content…
Figure 2
The graph above (Figure 2) shows the relationship between increasing the amount of sodium polyacrylate in each pillow and the absorbance of Copper and Cobalt. The slope indicates that the more sodium polyacrylate added to each pillow the less Cobalt and Copper absorbed from the heavy metal ion solution.
Figure 3
The graph above (Figure 3) represents the relationship between increasing the amount of sodium polyacrylate in each pillow and the volume of heavy metal ion solution absorbed by each pillow. The slope shows that as the more sodium polyacrylate inside the pillow, the more heavy metal ion solution is absorbed in each pillow.
Eight calculations were complete to obtain the amount of metal (Copper and Cobalt) absorbed by each pillow. Four calculations were used to calculate the amount of Copper absorbed by each of the pillows and the other four were done to calculate the amount of Cobalt absorbed by the pillows.
