Determination of adsorption capacity under static conditions

Abstract

The adsorption process are more and more frequently applied in water treatments. The choice of the adsorption medium depends on the adsorption capacity. The adsorption capacity in statical conditions should always preceeds the determination of the adsorption capacity in dynamic conditions, because it represents one of the main indicators of the proper determination of technological parameters in the process of water purification. The aim of this paper is to present a method for determination of specific adsorption capacity according to linear form of Freundlich`s equation and adsorption capacity in accordance with Lengmuir`s equation and its linear form.

Adsorpcioni procesi se sve češće primenjuju u tretmanima prečišćavanja vode. Izbor adsorpcionog medijuma zavisi od adsorpcionog kapaciteta. Adsorpcioni kapacitet u statičkim uslovima treba uvek da predhodi odreĎivanju adsorpcionog kapaciteta u dinamičkim uslovima, jer je on jedan od glavnih pokazatelja za pravilno odreĎivanje tehnoloških parametara u tretmanima prečišćavanja vode. U ovom radu prikazan je način odreĎivanja specifične adsorpcije prema linearizovanom obliku Freundlichove-ove jednačine i adsorpcionog kapaciteta u skladu sa Lengmuir-ovom jednačinom i njenim linearizovanim oblikom.
