The use of HCOOH enabled the direct determination of analytes in Zircaloys by ELCAD-AES. The improvement is 2-fold for most elements, 5-fold for Pb, and essentially unchanged for Cr. With 20% (v/v) HCOOH, improved detection limits were determined for Ni (5 ng mL −1), Co (9 ng mL −1), Fe (16 ng mL −1), Mn (7 ng mL −1), Mg (5 ng mL −1), Cu (6 ng mL −1), Cr (65 ng mL −1), Pb (10 ng mL −1), and Ca (8 ng mL −1). 20% (v/v) HCOOH was found to produce a maximum enhancement in the sensitivity of ELCAD-AES for the analytes. Sensitivity of ELCAD-AES was significantly improved with HCOOH for the determination of these elements. The influence of HCOOH and CH 3COOH to improve the sensitivity of ELCAD-AES for analyte determination is investigated. An electrolyte cathode discharge atomic emission spectrometry (ELCAD-AES) method using formic acid is described for the determination of major to trace level of the elements Ni, Co, Fe, Mn, Mg, Cu, Cr, Pb, Ca in Zircaloys.
