【摘要】 试验了用改性绿茶分离,冷原子吸收光谱法测定无机汞、烷基汞和苯基汞的条件,在pH5的溶液中吸附无机汞,与有机汞分离;在pH1的溶液中吸附有机汞,然后分别以1.5,3.0和6.0mol·l^-1盐酸解吸无机汞、烷基汞和苯基汞,用冷原子吸收光谱法测定汞,探讨了吸附机理,分析了牡蛎和水样中汞的形态.更多还原

【Abstract】 The conditions of the separation with modified green tea and cold vapour atomic absorption spectrometry determination of inorganomercury, alkylmercury and phenylmer-cury are examined. The inorganomercury and organomercury are adsorbed on the modified green tea at pH 5 and 1 respectively, and then inorganomercury, alkylmercury and phenylmercury are desorbed with 1. 5. 3. 0 and 6. 0mol·l-1 hydrochloric acid respectively and determined by cold vapour AAS. The adsorption mechanisms are approached. The inorganomercury, alkylmercury and phenylmercury in oyster and water samples have been determined.更多还原
