C18 bonded silica membrane disk modified with Cyanex 302 for Cr speciation and flame atomic absorption spectrometric determination

A new SPE method for speciation of Cr(III) and Cr(VI) has been developed using a Cyanex 302-impregnated C18 bonded silica membrane disk followed by flame atomic absorption spectrometric determination. The influence of various parameters, such as pH, flow rate, volume of sample solution, amount of Cy...
