A functiontalized organic-inorganic mesorporous material has been studied on preconcentration and determination of trace mercury.In this process,the effects of pH of solution,temperature,elution conditions on preconcentration of trace mercury were studied,and the effect of interfering ions was also investigated.The results showed that the material not only has highly selective affinity for Hg2+ but also large adsorbent volume.It was found that mercury could be adsorbed and eluted quantitatively on organic-inorganic mesorporous material at pH 3.2、 temperature(20±1 ℃).The static adsorption capacity of mercury on reported organic-inorganic material was 119.15 mg/g.Determination of trace mercury by atomic fluorescence spectrometry(AFS) after perconcentration on supported this material was eluted with concentrated HCl.The linear range was 0.005~5 ng/mL.The detection limit was 1.89×10-9 g/L(3σ). The RSD was 2.69%(n=11,c=0.5 ng/mL).The recoveries of mercury were 95.3%~104.5%.The method has been applied to the determination of trace mercury in water samples with satisfactory results.
