Fast and selective determination of ammonia in aqueous solutions using immobilized iron (III) oxide nanoparticles on the agarose membrane

Abstract: A highly selective and low-cost optical membrane for sensing aqueous ammonia
(NH3) based on the simultaneous production and immobilization of Fe2O3 nanoparticles
onto agarose membrane was prepared. Iron oxide nanoparticles were synthesized via mild
decomposition of iron (III) complex with Schiff base ligand N, N′-
disalicylidenetrimethylenediamine (Salpn) in aqueous solutions at 45° C. The proposed
method has no problems about fuel consumption and environmental pollution by toxic ...
