Regarding an experiment of the extraction of copper ions from a
copper solution using coffee grounds as an adsorbent
Will changing from regular to decaffeinated coffee grounds will
affect the absorbance of copper ions in a solution?
Also same applies with centrifugation, will placing the tubes
for longer times in the centrifuge affect the absorbance?
