Glassy carbon electrode modified by 25,27-dihydroxy-26,28-di(2’-Methyl-6-hydroxypyrimidine)thiopentaoxylcalix[4] arene-PVC was made.The electrochemical character of the modified electrode was investigated by Cyclic Votalmmetry in HCl,HNO3 and H2SO4.Effects of concentration of HCl and scan rate were discussed.The modified Glassy carbon electrode was found to be excellent respondence to Cd2+in 1mol/L HCl.The experiment parameters such as accumulation potential and time and scan rate were determined on Cadmium.It was found that the linear equation is Ip(μA)=10.95+2.430 lgc(mol/L)(r=0.9968).The concentration is in the range from 5.0×10-3to 8.0×10-7mol/L and the detect limit is 8.0×10-7mol/L.The method has been applied to the analysis of synthetic sample.The recovery of Cd2+is 98%. 展开更多
