研究了光谱法定量测定一氧化碳助燃剂中铂和钯的方法。当铂含量为１００×１０￣（－６）－６００×１０￣（－６）时，其标准偏差为３．４－４．６，回收率为９５％－９６％；当钯含量为３０×１０￣（－６）－３００×１０￣（－６）时，其标准偏差为２．６－４．１，回收率为９７％－９８％。方法的测定下限铂含量为３０×１０￣（－６），钯含量为１０×１００￣（－６）。
A spectrophotometric method for the quantitative determination of platinum and palladium in carbon monoxide combustion improvers was studied. When the platinum content is 100 × 10 -6 -600 × 10 -6, the standard deviation is 3.4-4.6 and the recovery is 95% -96%. When the content of palladium is 30 × The standard deviation was 2.6-4.1 at 10 -6 (-6) -300 × 10 -6 (-6), and the recovery was 97% -98%. Determination of the method of the lower limit of platinum content of 30 × 10 ~ (-6), palladium content of 10 × 100 ~ (-6).
