چکیده
|
A novel carbon paste electrode modified with zns/znal2s4 nanocomposite and an ionic liquid (zz/il/cpe) was fabricated and used for the electrochemical study of d-penicillamiene (d-pa). this modified electrode offers a considerable improvement in voltammetric sensitivity toward d-pa,compared to the bare electrode. square wave voltammetry (swv) exhibits a linear dynamic range from 5.0×10−7 to 3.0×10−4 m and a detection limit of 1.0×10−7 m for d-pa. finally,the proposed method was successfully applied to the determination of d-pa in real samples. © 2016 by cee (center of excellence in electrochemistry).
