Abstract: A DOUBLE JUNCTION REFERENCE ELECTRODE FOR USE WITH CHLORIDE SENSITIVE SENSORS COMPRISING: AN INTERNAL CASING (10) ENCLOSING AN INNER CHAMBER CONTAINING AN INTERNAL ELECTROLYTE (20), WITH A TOP CAP (12) COVERING ONE END AND A BOTTOM CAP (14) COVERING THE OTHER END; A REFERENCE ELECTRODE (25) PROTRUDING INTO INNER CHAMBER; AN EXTERNAL CASING (40) DISPOSED AROUND THE INTERNAL CASING (10) AND ENCLOSING AN OUTER CHAMBER BETWEEN SAID INTERNAL CASING (10) AND EXTERNAL CASING (40), OUTER CHAMBER CONTAINING AN EXTERNAL ELECTROLYTE (30) AND A TOP PLUG (42) COVERING ONE END AND A BOTTOM PLUG (44) COVERING THE OTHER END; AN INTERNAL JUNCTION BRIDGE (25) PASSING FROM THE INNER CHAMBER THROUGH THE BOTTOM CAP (14) AND INTO THE OUTER CHAMBER; AN EXTERNAL JUNCTION BRIDGE (35) PASSING FROM THE OUTER CHAMBER THROUGH THE BOTTOM PLUG (44) TO PROTRUDE OUTSIDE WHEREIN THE OUTER ELECTROLYTE (30) IS 5 TIMES THE CONCENTRATION OF THE INNER ELECTROLYTE (20) SUCH THAT THERE IS NO CHLORIDE IONS LEAKAGE.

Abstract: SELECTIVE LEAD (II) ION SENSOR (100) WITHOUT USING REFERENCE ELECTRODE IS USED TO MONITOR INDUSTRIAL DISCHARGE AND QUALITY OF WATER IN THE RIVERS, ESPECIALLY THOSE USED TO SUPPLY FRESH WATER FOR DAILY USE. THE LEAD SENSOR (100) OF THE PRESENT INVENTION COMPRISES MULTIPLE NARROW AND ELONGATED CHANNELS FILLED WITH LEAD RECOGNIZING MOLECULE (106), IMMOBILIZED BY LOW IMPEDANCE POLYMERIC BINDER (102). THE SENSING CHANNEL IS SANDWICHED BETWEEN AT LEAST TWO ELECTRODES (110) TO MEASURE THE CURRENT AND CONDUCTANCE ACROSS THE CHANNEL. THE BASELINE CONDUCTANCE OF THE CHANNEL IS ADJUSTED USING CONDUCTIVE PARTICLES (104) SUCH AS CARBON NANOTUBES AND PLATINUM NANOPARTICLES. THE DETECTION LIMIT AND LINEAR RANGE OF THE LEAD SENSOR (100) CAN BE OPTIMIZED BY CHANGING THE COMPOSITION OF THE MAIN COMPONENTS; LEAD IONOPHORE (106), LOW IMPEDANCE BINDER (102) AND CONDUCTIVE FILLER (104). THE PRESENCE OF TRACE AMOUNT OF LEAD ION CAN BE DETECTED FROM THE CHANGE IN THE CONDUCTIVITY ACROSS THE CHANNEL. THE PRESENCE OF LEAD IONS LINEARLY INCREASES THE CONDUCTIVITY OF THE SENSING CHANNEL. THE MOST ILLUSTRATIVE DRAWING IS
