## Abstract The metal content (Cu, Fe, Ni, Pb) of Finnish margarines manufactured in 1978β80 were investigated by the flameless atomic absorption spectrophotometry method. Copper, iron and nickel were digested by the dry ashing method whereas for lead both dry ashing and wet ashing were employed. T

An analytical method for the determination of iron, cobalt, nickel, and copper in aluminum fluoride has been described. The insolubility of \(\mathrm{AlF}_{3}\) in inorganic acids makes it necessary to separate these metals by leaching them with \(\mathrm{HNO}_{3}\). The metals that leached out were
## Abstract A simple and reproducible method for the rapid extraction and determination of trace amounts of copper(II) ions using octadecylβbonded silica membrane disks modified by 1,5βdiphenylcarbazide (DPC) and atomic absorption spectrometry was presented, which was based on complex formation on
