| Abstract: | A novel method for the preconcentration and separation with crosslinked chitosan and determination of trace manganese in environmental samples by flame atomic absorption spectrometry has been presented.The optimum adsorption and elution conditions have been studied.The effect of co existing elements also investigated.The detection limit of the method is 2.6μg/L with RSD of 2.9%.The method has been applied to the determination of trace manganese in the standard samples of oyster and hair with satisfactory results. |
