Table 2 Recovery of Tl(I) and Tl(III) from samples prepared by standard solution

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

Tl species Tl(I):Tl(III)
1:0 (%) 0:1 (%) 1:1 (%) 10:1 (%) 50:1 (%) 100:1 (%)
Tl(I) 100 ± 2 0.2 ± 0.1 101 ± 4 103 ± 6 99 ± 2 97 ± 6
Tl(III) 0.3 ± 0.03 99 ± 1 98 ± 4 100 ± 0.8 106 ± 2 109 ± 1
Total Tl 100 ± 2 99 ± 1 100 ± 4 102 ± 5 99 ± 1 97 ± 6
  1. The samples, all of 10 mL volume, contain 350 ng Tl(I) (1:0 column), 380 ng Tl(III) (0:1 column), or solutions containing 380 ng Tl(III) and concentrations ratios of 1-, 10-, 50- and 100-fold larger of Tl(I) in 10 mL samples were tested. The results are presented as mean values ± SD (n ≥ 3)
