A simple method for the quantitative determination of Nickel in Vanaspati by EDXRF is described. The nickel spiked fat was taken in platinum crucible and heated at 800°C in muffle furnace with sodium carbonate thereafter the ash was dissolved in HCl:HNO3 (1:3). The quantitative determination of Nickel was carried out by Energy Dispersive X ray Fluorescence Spectrophotometer after optimization of the instrumental parameters. Results from spike and recovery experiments at levels of 20 and 50 ug g−1 are 95–110%.
