摘要: Abstract A method is described for the incorporation of urease into a polypyrrole film by galvanostatic polymerisation on gold-coated plastic films and solid gold electrodes. The presence in was verified x-ray photoelectron spectroscopy, amino acid analysis, scanning microscopy cyclic voltammetry. enzyme activity polypyrrole-urease confirmed its catalytic conversion urea to carbon dioxide ammonia. use both spectrophotometric potentiometric methods detection their potential determination discussed.
