Removal behaviors and mechanisms of hexavalent chromium from aqueous solution by cephalosporin residue and derived chars.

abstract：:A two-stage membrane process for the separation of galactose, 5-hydroxymethylfurfural (5-HMF) and levulinic acid (LA) has been proposed. The first step of nanofiltration (NF) is to remove 5-HMF and LA from galactose solution obtained by the hydrolysis of agarose, the main component of red algal galactan for the reduct...
