11. Calcium oxide is often referred to as the " sorbent ". 12. But in all other cases cartridges will be replaced with partially used sorbent . 13. LDH minerals as hydrotalcite are powerful anion sorbents but are relatively rare in nature. 14. Finally, contaminants transfer from the membrane into the sorbent material mainly through adsorption. 15. Also, developmental versions of a Wearable Artificial Kidney have incorporated sorbent -based technologies. 16. Alternatively, pumps and sorbent tubes are placed in areas for fixed-point sampling. 17. Currently, researchers are developing new sorbents with higher adsorption ratio to optimize this process. 18. The PES membrane acts as a semipermeable barrier between the sorbent and surrounding aquatic environment. 19. The solvent used is specifically chosen based on the type of sorbent and chemicals sampled. 20. As explained above, alkaline sorbents are used for scrubbing flue gases to remove SO 2.
