Description |
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 extracted species for thallium(I): cryptand 222: erythrosin was 1:1:1. The separation of thallium(I) from several elements, and its determination in spiked sediments, was possible.
