ANODIC STRIPPING VOLTAMMETRIC DETERMINATION OF LEAD USING A CHEMICALLY MODIFIED ELECTRODE BASED ON AZA CROWN ETHER

ANODIC STRIPPING VOLTAMMETRIC DETERMINATION OF LEAD USING A CHEMICALLY MODIFIED ELECTRODE BASED ON AZA CROWN ETHER

A glassy carbon electrode was modified by drop-coating technique using 1,4,10,13-Tetraoxa-7,16-diazaciclooctadecano (diaza-18 -crown-6 or DA18C6) and Nafion (NF) for the determination of Pb (II) by square wave anodic stripping voltammetric (SWASV). The new electrode exhibits an increase in due to ma...
