The invention discloses a method for recovering
cefprozil from
cefprozil crystallization mother liquor. The method is characterized in that the absorption,
desorption and
crystallization treatment is performed on the cooled
cefprozil crystallization mother liquor by adopting
macro-porous resin, and the purified cefprozil is recovered. The method comprises the following steps: by utilizing the
macro-porous resin, in combination with the cooperation of the adsorption conditions of specific pH, temperature and flow rate and the
desorption conditions of certain pH, temperature and flow rate of a specific analytical solution, effectively absorbing and efficiently desorbing the cefprozil remaining in the efprozil crystallization
mother liquor through the
macro-porous resin and recovering; finally de-coloring, crystallizing, filtering and
drying the analytical solution to obtain a high-purity cefprozil product conforming to qualified
product standard requirements. The method disclosed by the invention is high in
recovery rate, simple and convenient to cooperate, low in cost, green and safe; and the residue of the cefprozil in the cefprozil crystallization mother liquor after
recovery treatment is less than or equal to 1 mg / ml, so that the COD value of
wastewater can be effectively reduced, and the
environmental protection pressure and the
wastewater treatment cost are reduced, and therefore, the economic and
social benefits are significant.
