摘要 |
<p>The present invention relates to the synthesis of immobilized nitrate ionophores (IV) and (Vl) to be used as ion recognition molecules for nitrate anion (NO3 -) 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 ionic species in soil, tree sap, ground water and river.</p> |
