Thallium(I) was quantitatively extracted, at pH 6.5, with 1 x 10 -3 M cryptand 222 in chloroform with 1 x 10 -3 M erythrosin as the counterion. From the organic phase it was stripped with 0.1 M sulphuric acid and was determined by atomic absorption spectrometry at 276.8 nm. The composition of extrac
The extraction of copper(I1) ions in the presence of salicylate ions, using a solution of the salicylate form of Aliquat 336 in chloroform, involves two simultaneous processes depending on the pH and on the salicylate concentration of the aqueous phase. The composition of the species formed in the c
