The influence of some conditions and factors on chrome was determined by flame atomic absorption spectroscopy (F-AAS) have studied. The conditions for chrome determination by F-AAS have investigated as: A (357.9nm)
high cathod lamp (8mA)
burner height (6mm)
acid (HCl 2 percent)
matrix (NH4Ac 1 percent + LaCl3 1 percent)... The influence of some metal ions and some anions (K+, Na+, Ca2+, Mg2+, Fe2+, SO4, PO4,...) on chrome determination by F-AAS also has investigated. All of the experimental data were treated by statistics and Minitab 14 software.
