CATALASE ENZYME ELECTRODE AND ITS PROPERTY
Abstract:
A catalase membrane immobilized on a nylon net was prepared, using freshly synthesized triethylonium tetrafluoroborate as immobilizer. The membrane had an activity of 80unit/cm2,while that immobilized by dimethyl sulfate showed an activity only of 35, 6unit/cm2.The catalase electrode showed linear response within 5,0×10-6~5,0×10-4mol·L-1,with detection lirit of 4,0×10-6mol·L-1 and 95,2% recovery.Its service life is more than 500 times. SO42-, Cl-, NO3-,NH4+,Ac-,glycine,glueose etc. do not interfere with the detection.
