PREPARATION OF MONOBASIC PHOSPHATE IONOPHORES
The present invention relates to the synthesis of lipophilic or immobilized monobasic phosphate (H2PO4) ionophores (7, 8a, 8b and 11) to be used as ion recognition molecules for monobasic phosphate (H2PO4") in the cocktail preparation of hydrophobic polymer membranes in ion selective electrode (ISE) or ion-sensitive field effect transistor (ISFET) chemical sensors for detection of monobasic phosphate (H2PO4 ) ionic species in soil, synthetic media, hydrophonic liquid, tree sap, ground water and rivers.
