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．
The interference of aluminum on iridium in hydrochloric acid, nitric acid and sulfuric acid was studied. The interference of aluminum on iridium showed a desensitization effect in hydrochloric acid medium and a sensitization effect in sulfuric acid medium. In the nitric acid medium, a small amount of aluminum had an inhibitory effect on the absorbance of iridium, but increased as the concentration of aluminum increased Sensitization of 4000 μg / mL aluminum sensitized iridium at 0-200 μg / mL to approximately 400%, and iridium can be measured using standard addition conditions at this condition, which is also resistant to interference with 400 μg / mL iron at 200 μg / mL This article also discusses the interference mechanism of aluminum on iridium.
