Research of Calixarene Derivatives Modified Electrode Electrochemical Performance

Using 5,11,17,23-tert-butyl-25,27-dihydroxy-26,28-2（ethoxycarbonyl-methoxyphenyl） calix 4] arene（ester-calix 4] arene） modified glassy carbon electrode,the electrochemical behavior of Pb2＋ at this modified electrode was studied.Experiments showed that： the modified electrode was non-oxidation process in the basic system;In the acid system,the modified electrode was good electrochemical activity,and this modified electrode had a high sensitivity to Pb2＋ and the linear scanning stripping voltammetric peak current was linear with Pb2＋concentration in range of 3.65×10-6 mol·L-1~4.83×10-3 mol·L-1 with the detection limit of 1.28×10-6 mol·L-1.
