Özet
The interference on the determination of nickel by the salts LiCl, NaCl, KCl, CsCl, NH4Cl, Na2SO4, NaNO3, NaC2H3O2 in an inductively coupled plasma-atomic emission spectrometry has been carried out. The salt concentration was in the 100-10000 mg L-1 range. Nickel emission was enhanced at lower matrix concentrations (100 mg L-1) and was depressed at higher matrix concentrations (10000 mg L-1). Except cesium, above 100 mg L-1, all studied ions caused a decrease in the signal intensity in the range of 0-15%. The sequence order of the investigated ions for the enhancement and depression was unstable. The sequence order in enhancement was found as Li+ < Na+ < K+ < Cs+ < NH4+ for cation; NO3- < SO42- < Cl- < OAc- for anions and Cs+ < NH4+ < K+ < Li+ < Na+ for cat-ions and OAc- < SO42- Cl- < NO3- for anions in depression at the studied lines.
