【摘要】 本文提出一种同时测定两组分的新方法,即双波长K系数-标准加入分光光度法。该法同时进行两组的标准加入,以两个组分的最大吸收波长为测定波长,又互为参比波长,以一套吸光度数据同时完成两个组分的测定。本法已用于重油中钴、镍的同时测定,结果满意。更多还原

【Abstract】 A new method for the simultaneous determination of two components is proposed,namely,the K coefficient standard addition dual wavelength spectrophotometry.The proposed method overcomes the drawback of the conventional dual wavelength standard addition spectrophotometry which sometimes fails to give reproducible absoprption points.The method has been applied to the determination of cobalt and nickel by using the OP 5 Br PADAP system.The results are satisfactory.更多还原
