【摘要】 <正> 生物传感器是一种新兴的测试工具,其中酶电极因具有较常规离子选择电极更短的响应时间,更好的选择性与抗干扰能力强等特性,引起了人们的关注。本文用新鲜合成的三乙基更多还原

【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. SO₄^2-, Cl^-, NO₃^-,NH₄⁺,Ac^-,glycine,glueose etc. do not interfere with the detection.更多还原
