Abstract
A FIBER OPTIC CHEMICAL SENSOR (FOCS) IS PROPOSED FOR IN-SITU DETECTION OF HYDRAZINE IN WATER. IN PHASE I, BOTH FLUORESCENCE AND ABSORBANCE TECHNIQUE WILL BE USED TO OBTAIN A PROTOTYPE WORKING SENSOR. IN THE FIRST METHOD, THE FLUORESCENCE OF YELLOW COLORED AZINE (EXCITATION 466 NM; EMISSION 546 NM) PRODUCED BY THE REACTION OF HYDRAZINE WITH 4-DIMETHYLAMINO BENZALDEHYDE WILL BE USED. IN THE SECOND METHOD, ABSORBANCE OF ORANGE YELLOW CUPROUS NEOCUPROINE CHELATE (MAX. 458 NM) THAT IS PRODUCED FROM HYDRAZINE - COPPER(II) NEOCUPROINE REACTION WILL BE MONITORED. IN BOTH APPROACHES, THE COLORED PRODUCTS ARE EXPECTED TO FOLLOW BEER'S LAW OF LINEARITY AND HENCE IT WILL BE POSSIBLE TO OBTAIN HYDRAZINE CONCENTRATIONS IN UNKNOWN SAMPLES USING A CALIBRATION CURVE. THE BEST WORKING OF THE ABOVE REACTIONS WILL BE CHOSEN FOR ADAPTATION TO SOLID STATE FOCS DURING PHASE II.
