21. Beyond that point rate of adsorption saturates even after applying higher pressure. 22. Here the grain boundary analogue of Langmuir adsorption at free surfaces becomes: 23. Polymer chains are grafting to a surface via covalent bonding or adsorption . 24. OK, so now say that another light color adsorption chemical appears. 25. The enthalpy of adsorption can determined from constant pressure calorimetry: 26. The thickness of a polyelectrolyte then affects its adsorption ability. 27. The biogeochemistry of arsenic is complex and includes various adsorption and desorption processes. 28. As an adsorption chiller requires no moving parts, it is relatively quiet. 29. Ethanol is subsequently isolated and purified by a combination of adsorption and distillation. 30. The cooled offgas may be treated by carbon adsorption , or thermal oxidation.
