Abstract

The bis[undecahydro-7,8-dicarbaundecaborato(2-)]cobaltate(1-) (X<sup>-</sup>) has been used for complementary study of its ionic associates with some cations of organic bases and quaternary salts. For the optimization of present analytical methods, quinuclidin-3-yl hydroxy(diphenyl)acetate, 1-(1-phenylcyclohexyl)piperidine, dibenzo[<i>b,f</i>][1,4]oxazepine and cocaine, were studied by competitive extraction method. X<sup>-</sup> labelled with <sup>60</sup>Co was used as carrier anion, triphenylmethane and azo dyes as competitive anions. The aqueous phase was 0.1 and 0.01&nbsp;M HCl, the organic phase was chloroform. A comparison was made with earlier results obtained by extraction spectrophotometry.
