【摘要】 研究了铝在盐酸、硝酸和硫酸介质中对铱的干扰规律．铝对铱的干扰在盐酸介质中表现为降感作用，在硫酸介质中表现为增感作用，在硝酸介质中，少量铝对铱的吸光度有抑制作用，随着铝浓度的增加则表现为增感作用，4000μg/mL的铝使0～200μg/mL的铱增感约为400％，在该条件下可使用标准加入法测定铱，该条件还可抵抗400μg/mL铁对200μg/mL的干扰，本文还探讨了铝对铱的干扰机理．更多还原

【Abstract】 In this paper, the interference of aluminiun with the determination of iridium in the media of hydrochloric acid, nitric acid and sulphuric acid in air-ethyne FAAS has been studied, In the medium of hydrochloric acid, Al depresses Ir signal in the medium of sulphuric acid, Al enhances Ir signal. In the medium of nitric acid, micro Al depresses Ir signal, with the increase in the concentration of Al, it increases the Ir signal. 4000μg/mL Al increases 0-200μg/mL Ir signal to about 400%. The mechanism, method of elimination interference and application of interference were discussed.更多还原
