摘要
本文研究了Ｇｄ（Ⅲ）－三氟乙酰丙酮－ＣＴＭＡＢ的三元配合物荧光体系，并用于钆的测定，最低检测限为：０．００３μｇ／ｍＬ，Ｇｄ在０．００５～０．４μｇ／ｍＬ范围内呈线性关系，回归方程Ｆ＝３１．６５ｃ＋０．２１，相关系数为ｒ＝０．９９９６，将此法用于稀土矿的痕量Ｇｄ的测定，与ＩＣＰ－ＡＥＳ法相比，结果令人满意。
The determination of microamount gadolinium(Ⅲ) by fluorescence method was studied based on complex formation Gd(Ⅲ) CTMAB TFA at pH7 2.Beer′s law is obeyed in the range of 0 005～0 04μg/mL Gd(Ⅲ).The detection limit is 0 003μg/mL. The method is used to determine microamount gadolinium of rare earth mine with satisfactory result,and compared with that of ICP AES method.
