Eggshell Membrane Biomaterials for Adsorption and Determination of Mn(II, VII) in Environmental Water

Abstract:

A simple solid phase extraction procedure for adsorption and preconcentration of manganese(II, VII) in environmental water samples has been proposed prior to inductively coupled plasma mass spectrometry. The procedure presented based on quantitative recoveries of manganese >95%. In this work, the potential use of eggshell membrane(ESM), a typical biomaterial, as solid-phase extraction (SPE) adsorbent is evaluated for analysis of trace manganese. The analytical variables, pH, flow rate, sample volume, elution, coexisting ions for optimum recoveries of manganese (II) and manganese (VII) were investigated. The preconcentration factor was 60. The detection limit (3) of manganese was 0.031 ng L-1. The relative standard deviations of determination was found to be 3.21%. The procedure was successfully applied to the adsorption and determination of manganese in environmental water samples.
