The standard addition and successive dilution method for evaluation and verification of results in atomic-absorption analysis.
A simple procedure for evaluation and verification of results obtained by atomic-absorption analysis is proposed. It allows estimation of the correct results in the presence of unknown strong interferents and does not require any preliminary information about the sample to be analysed. The concept of the procedure arises from theoretical considerations of various types of interference effects on the form of calibration curves. The procedure may be considered as a combination of the standard addition and successive dilution methods. Although the procedure was developed and tested for atomic-absorption analysis it seems to be applicable to all analytical techniques in which preliminary elimination of non-specific interference signals that are independent of the analyte concentration is possible.
