| Abstract: | Based on the application of aqueous two-phase flotaion(ATPF) in the separation and concentration of penicillin from aqueous phase,the separation behavior of penicillin in the ATPF process was investigated.The kinetic behavior and the penicillin status in organic phase were studied under the conditions of room temperature,300 mL penicillin aqueous solution of 2.5 g/L,initial pH 7.0,ammonium sulfate concentration of 350 g/L,10 mL polyethyleneglycol(PEG) aqueous solution(50%,w/w).Using three flow rates,the kin... |
