Detection of inorganic anions by the immobilized Schiff-base receptor on zeolite-Y

Research on design and synthesize of molecular sensors for detection anions is very important, because of the present anions in biological, agriculture, environmental, pharmacologic and industrial [1-4]. Among variety important anions, hydrogen sulfate anion takes more attention; this anion may be exist in sewage industrial and agriculture fertilizer so can pollute surface water and ground water [5-6]. The PH water was made decrease dramatically by anion bisulfate, so presence of HSO4- anion in water causing irritation skin and eyes [7]. Already most of the molecular sensor works in organic solvent or blend of organic solvent and water. In other hand many studies reported to detect of HSO4- by free molecular sensor based on hydrogen band that has low sensitivity [8-9]. In this paper we synthesize a molecular sensor was immobilized on the zeolite, that can detection mention anion in aqueous solvent and mechanism detection is based on break band Schiff base
