摘要：

A kinetic spectrophotometric method for the determination of trace iridium (Ⅳ) has been established, which is based on its catalytic effect of the oxidative color reaction of diantipyryl-(o-chloro)- phenylmethane (DAoCM) with potassium periodate. It has been applied to the determination of trace iridium in ores.
