Abstract
It is important to understand the fate of Lipitor (atorvastatin calcium) in wastewater treatment system due to its persistence and the harmful effects that it might cause to the humans and nature. Laboratory experiments were carried out to study the sorptive behavior of Lipitor in XAD4, XAD7HP, XAD16, activated carbon (AC), and sand. The 7-day or 14-day isotherm experiments were conducted to compare the sorption capacities of these selected adsorbents. The objective of these isotherm studies was to determine the most suitable adsorbent(s) to remove Lipitor from synthetic wastewater made using cat food and tea. Results showed that AC was most effective in removing atorvastatin, followed by XAD4, XAD7HP, and XAD16 resins, while sand showed no significant effect in the sorption of atorvastatin.
