Regularities of sorption processes in the lichen meal system Cladonia sylvatica - water solution Zn (II)
The processes of sorption of water and zinc ions were studied in static and dynamic conditions by meal lichen Cladonia sylvatica. The sorption characteristics of meal lichen were evaluated concerning water molecules and ions Zn (II) by using the quasi-chemical model sorption and Langmuir Dubinin-Radushkevich's models sorption. Due to investigation of the possible sorption devices it was shown that the predominant value was physical ions Zn (II) adsorption of hydroxyl groups on the sorbent. The equilibrium and kinetic characteristics of adsorption and optimum pH range of maximum sorption capacity of meal lichen on the zinc ions' base were defined.
