Özet:

 


A (2,3,7,8,12,13,17,18-Octakis(4-tert-butylbenzylthio)-porphyrazinato)Mg(II)
functionalized quartz crystal microbalance sensor has been developed
for the detection of trace Cd2+ions in water samples. The quartz crystal microbalance results indicated
that the MgPz coated sensor exhibited high sensitivity, stability and
selectivity for the detection of Cd2+ in aqueous solution. The
lowest detection limit can reach 10 mg/ml Cd2+ in aqueous solution, which resulted in the
frequency shift of ~ 150 Hz. The observed adsorption data were analyzed using four adsorption
kinetic models; the Elovich equation, Ritchie’s equation, pseudo first- and
second-order equations. Results show that the linear regression analysis with
respect to pseudo-second-order  rate
equation generates a straight line that best fit to the data of adsorption of Cd2+ on Pz film.
