During research work on Non-Ferrous Metals Faculty concerning on the new corrosion inhibitors of iron alloy in magnetic field, Ho3+ ions were proposed as one of the new inhibitors. One of the methods to determine the rate of corrosion process is determination of concentration of Fe ions in solution. Due to required high precision of the determination of the concentration Fe ions in solution contains Ho3+ ions in a wide range of concentrations, the influence of matrix effect and interferences of Ho3+ ions must be known. The present work investigates the impact of Ho ions in rang 0 to 100 mg/L for the quantitation of Fe ions in 0.1 M HCl solution using MP-AES method. Obtained results were analyzed using single-factor ANOVA method. In range up to 40 mg/L Ho3+ ions is not significant factor to determination of Fe concentration by MP-AES.Downloads
