【摘要】 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）。更多还原

【Abstract】 In this paper,a method for the quantitative determination of platinum and palladium inthe combustion improver-carbon monoxide using spectroscopy is studied.For a platinum con-tent of 100-600 ppm,the standard deviation is 3.4-4.6,and the recovery ratio lies be-tween 95-96%;for a palladium content of 30-300ppm,the standard deviation is 2.6-4.1,the recovery ratio is 97-98%,the lowest limit of detection is 30ppm for platinum and 10ppm for palladium.更多还原
