Kinetics and thermodynamic studies on sorption of NPs by ECDMZ from aqueous solution
View through CrossRef
Abstract
The sorption kinetics of NPs from aqueous solutions by ECDMZ was researched. The experimental results indicated that the sorption of ECDMZ fits the second order dynamic equation. It is showed that the chemical sorption process should be the main factor of controlling sorption rate. Meanwhile, the thermodynamic of NPs from aqueous solutions by ECDMZ were studied too. The thermodynamic research revealed that the whole sorption was exothermic and spontaneous process. In the studied range of 20∼100 mg?L−1, Enthalpy change dominated the whole chemical sorption process. Temperature had little effect on the sorption process in the studied range of 288∼308 K.
