Glycerokinase( GK) and glycerol-3-phosphate oxidase( GPO) were immobilized to develop glycerol enzyme membrane and enzyme electrode for determination of glycerol concentration. Results showed that the higher current output for glycerol was obtained using a 1∶ 1( GK∶ GPO) ratio for the random immobilization.The efficient two-enzymatic membrane was prepared by immobilizing GK in nuclear pore film coupled with GPO on Biodyne B. Glycerol enzyme electrodes were realized by assembling the GK-GPO membranes previou...
