摘要： An improved apparatus for detecting anions in water includes an electrical continuous ion-exchange unit comprising an anode compartment and a cathode compartment which are spaced apart by an alkali removing compartment packed with a cation exchanger defined by two cation-exchange membranes. Each of the said anode compartment, cathode compartment and alkali removing compartment is provided with a passageway through which water is admitted and a passageway through which the treated water is discharged. The passageway through which the treated water is discharged from the alkali removing compartment is equipped with an instrument for measuring the specific resistance or electrical conductivity of the treated water. The alkali removing compartment may be replaced by one or more cation-exchange membranes or a treatment compartment defined by two or more cation-exchange membranes, and the passageway through which the treated water is discharged from the anode compartment is equipped with an instrument for measuring the specific resistance or electrical conductivity of the treated water. The apparatus does not require replacement of ion-exchange resins, achieves correct measurements with a simple operation and yet functions as an inexpensive salt detector.
