Abstract
⺠An on-line separation/preconcentration procedure using EVA has been coupled to the zinc vapor generation was studied. ⺠The zinc was retained as precipitate on the column without any complexing agent. ⺠Volatile species of zinc were generated with sodium tetrahydroborate in a continuous flow system. ⺠Multivariate techniques (two level factorial design and central composite design) were used for optimization of analytical methods. ⺠An enhancement factor of 230-fold was obtained and the detection limit was 0.06 μg Lâ 1.
