A Study on the Affinity of Fe2+ and Zn2+ for Im-SH Self-Assembled Film on Piezoelectric Quartz Crystal

In this work, the affinity of Fe 2+ and Zn 2+ for Im-SH group were investigated in the electrolyte solution of FeCl 2 and ZnCl 2 using quartz crystal analyzer (QCA). Imidazolyl-Alkanethiol (Im-SH) was coated on a side of quartz crystal electrode by the process of self-assembly. The result shows that...

Description
Summary:In this work, the affinity of Fe 2+ and Zn 2+ for Im-SH group were investigated in the electrolyte solution of FeCl 2 and ZnCl 2 using quartz crystal analyzer (QCA). Imidazolyl-Alkanethiol (Im-SH) was coated on a side of quartz crystal electrode by the process of self-assembly. The result shows that the reaction of Zn 2+ for Im-SH film is stronger them that of Fe 2+ and the substitution reaction rises on (Im-SH)-Fe 2+ film in the electrolyte solution of ZnCl 2 , whereas the (Im-SH)-Zn 2+ film is stable in the electrolyte solution of FeCl 2 .
