Table 3 The recovery of Tl(I) and Tl(III) from samples at different pH

From: A modified method of separating Tl(I) and Tl(III) in aqueous samples using solid phase extraction

pH Tl(I), % Tl(III), % Total Tl, %
pH = 1 102 ± 1 100 ± 6 101 ± 3
pH = 2 98 ± 6 104 ± 6 101 ± 6
pH = 3 97 ± 3 101 ± 2 99 ± 2
pH = 4 95 ± 4 98 ± 0.8 97 ± 2
pH = 5 97 ± 3 99 ± 0.3 98 ± 2
pH = 6 97 ± 2 101 ± 2 99 ± 2
pH = 7 97 ± 0.2 103 ± 3 100 ± 2
  1. The samples at pH from 1 to 7 contain 3500 ng Tl(I) and 3800 ng Tl(III) in 3–8 mL. The results are presented as mean values ± SD (n ≥ 3)
