A new, sensitive calorimetric method for the estimation of 6-aminopenicillanic acid is described. The procedure is based upon formation of a 2,4-pentanedione derivative of 6-aminopenicillanic acid followed by a second reaction with p-dimethylaminobenzaldehyde (Ehrlich's reagent), resulting in a red
## Abstract The separation behavior of phenylacetic acid (PAA), 6โaminopenicillanic acid (6โAPA) and penicillinโG (PenโG) with electrodialysis under constant current was studied. The effects of ionic concentrations and current density on their separation behavior were investigated. The sorption of
