A new method for on-line solvent extraction covalent hydride generation in a non-aqueous media was proposed. Flow injection techniques were used to develop an efficient on-line solvent extraction pre-concentration and pre-separation system. The hydride generation is carried out in an aliquot of metal-complex extraction solution by sodium tetrahydroborate(III) in N,N-dimethyl formamide solution and anhydrons acetic acid. Hg is extracted by KI + HNO3 + (NH2)2CS into TBP and hydride generation by proposed method. A improved u-type gas-liguid separator was used. The working conditions and manifolds scheme of flow injection had been optimized. The method is applied to the determination of mercury in GSD-4 and GSD-6 geological reference materials with good accuracy and precision.
