Electrochemical determination of perchlorate ion by polymeric membrane and coated graphite electrodes based on zinc complexes of macrocyclic ligands

- Two Zn complexes I1 and I2 were synthesized.
- Zn complexes were used for the construction of PME & CGE for determination of perchlorate.
- CGE is found to be better with respect to PME.
- CGE were used to determine perchlorate ion in water and human urine samples.
