摘要
本文研究了钪-铬天青S-镧-邻菲琳配合物的形成条件及其有关反应过程。配合物的最大吸收峰位于610nm,相应的摩尔吸光系数为ε_610=3.25×10 ̄4L·mol ̄-1·cm ̄-1.配合物中各组分的摩尔比Sc:CAS:La:Phen=2:6:3:3,相应的分子式为[Sc(CAS)_3]_2[La(OH)Phen]_3.
This paper reports the colbr reaction of chrome-azurol-phen complex for scandiumand lanthanum. The polynuclear complex exhibits an absorption maximum at 610 nm and itsmolar absorption was found to be 3.25×10 ̄4L·mol ̄-1·cm ̄-1.The molar ratio in the com-plex is Sc : CAS : La : Phen=2 :63:3.The color reaction has been applied to the dorect deternunation of scandium in lanthanum base xynthetic sample with satisfactory resuIts.
