The appropriate pH range for the analysis was 4.5-6.0. The complexing agent studied, tri-sodium citrate, was observed to be the most efficient masking agent for Al, Fe, Ca and Mg. Even a large excess of elements with high stability constant does not interfere with it. The accuracy and precision of the method was evaluated. The method has been applied for drinking and river water samples.
