GF-AAS DETERMINATION OF TRACES OF TIN IN WASTE GAS FROM REFUSE INCINERATION WITH ZEEMAN EFFECT-BACKGROUND CORRECTION

A GF-AAS method was established for the determination of trace amounts of tin in waste gas from refuse incineration.Palladium nitrate and ascorbic acid were selected as matrix modifier.Zeeman effect was used for the correction of background absorption.Detection limit of the method was 100 pg (3σ).Linearity was in the range of 10-200 μg·L-1.Results obtained by test for recovery were in the range 96.8%-102.0%.
