Abstract
A lieterogeneous precipitate has been as ion carriers for the
preparation of urea and oxalic acid selective membrane sensor. The
electrodes give near-N'emstian response in the linear concentration range
of 1 M to 1x10' M \s ith detection limits of ilie orders of lO"* M . fhe stable
potentiometric signals are obtained \Gth in a short time period ot 3
seconds. Tlie effect of pli and the effect of medium have been studied,
found to give a better responses selectisit) coefficient \alues
pot
( log ) and ( log o^al'cacid n.xed
interference method. Tlie sensors have also been used as urea
determination in fertilizers.
