A NEW TECHNIQUE FOR EASY, FASTER AND ACCURATE ANALYSIS OF BABBITT METALS (LEAD AND TIN BASE, WHITE METALS) BY ICP VIA FORMATION OF HIGHLY SOLUBLE TARTARATE SALTS

摘要

This invention relates to a process for the analysis of Babbitt metals comprising the steps of preparing a solution of hydrochloric acid and dltartaric acid to a sample of the Babbitt metal to form a mixture, followed by heating the mixture for complete dissolution, to form a solution; cooling the solution, adding a cobalt solution thereto and making up to the required volume using hydrochloric acid, to obtain the Babbitt metal solution, subjecting the Babbitt metal solution to spectrophotometric analysis using inductively coupled plasma atomic emission spectroscopy (ICP), with the nebuliser flow at 8 to 8.5 lit/min, the auxiliary flow 2 lit/min, and the torch position at 0.4 m vertical and 4.8 mm horizontal.
