| 中文摘要 | a method was developed for the determination of total mercury in biological samples. the effects of aqueous ammonia, ethylenediamine and triethanolamine on hg signal intensity by inductively coupled plasma mass spectrometry has been evaluated and the possible mechanisms discussed. it has been proved that the signal intensity of hg significantly increases with adding, in the presence of small amounts of aqueous ammonia, ethylenediamine or triethanolamine. the normalized intensity (the signal intensity ratio with amine and without amine) of hg increases as the concentration of aqueous ammonia, ethylenediamine or triethanolamine increases, but the degree of enhancement of aqueous ammonia was smaller than that of ethylenediamine and triethanolamine. the normalized intensity of hg with aqueous ammonia, ethylenediamine and triethanolamine decreases as the nebulizer flow rate increases, but decreasing degree of aqueous ammonia was smaller than that of ethylenediamine and triethanolamine. the higher the rf powers the higher the normalized intensity of hg at the same nebulizer flow rate. the addition of aqueous ammonia, ethylenediamine and triethanolamine into analytical solutions significantly improved the transport efficiency of hg. the detection limit of hg is improved about ten times by the addition of ethylenediamine or triethanolamine under the optimum experimental parameters. the method has been used to determine mercury in biological standard reference materials (srm). the analytical results are very close to the certified values and the determined values for similar samples. |
