Abstract:

 A new potassium ion-selective membrane electrode has been developed based on heterogeneous precipitate and the membrane was development using epoxy resin. An analytically useful potential changes occur in the 1 to10-3M concentration range of KCl. The slope of the linear portion (1x10-1-1x10-3 M) was 55mv/decade. The stable potentiometric signals are obtained with in a short period of 7 seconds. In the presence of 1x10-4M potassium no interference was observed for Na+, Mg2+, Ba2+, Mn2+, ,Ni2+, Cu2+, F- , Cl-, Br-, I-,SO42- ions. The effect of pH and effect of medium have been standardized found to give better response life time of the electrode was approximately 3 months. This electrode has been used for the determination of potassium ion commercially available product.
