Extraction of selected incapacitating agents by bis-1,2-dicarbollylcobaltate anion from water into chloroform

Bis-1,2-dicarbollylcobaltate anion, labelled by ⁶⁰Co, forms ionic associates with cations of some incapacitating agents. Their stability and partition between aqueous 0.1 mol.L⁻¹ HCl and chloroform were investigated radiometrically. A method of competitive extraction was proposed for some anions of dyes which were so far used for extraction-spectrophotometric determination of some agents.
