Electrospun cationic nanofiber membranes for adsorption and determination of Cr(vi) in aqueous solution: adsorption characteristics and discoloration mechanisms

Cationic nanofiber membranes are prepared by electrospinning mixed aqueous solution of a cationic polycondensate (CP) and PVA. Apart from being a highly efficient Cr( vi ) adsorbent, it can also serve as a convenient method for Cr( vi ) determination.
