Abstract: The urea decomposition caused by urease in the presence of some inhibitors: nicked nitrate,phosphates,and EDTA has been studied by tising a NH3-gas selective electrode. The mechamism of the decomposition reaction has been discussed.

Key words: urea decomposition, urease, nicked nitrate, phosphate, EDTA, inhibition
