摘要：

A procedure is described for the extractive photometric determination of copper (II) with thiothenoyltrifluoroacetone (STTA) in carbon tetrachloride. The olive brown Cu (II)-STTA chelate solution in carbon tetrachloride obeys Beer's law over the concentration range of 1.23 to 12.35 m9 of Cu per ml. Between pH 2 to 5, quantitative extraction is feasible with 0.001M STTA in carbon tetrachloride. The color of the complex is stable to 72 hours. Copper (II) can be extracted rapidly and determined in the presence of large numbers of cations as well as anions. © 1969, American Chemical Society. All rights reserved.
