Titrimetric determination of sulphate in natural waters using lead ion-selective electrode detector

R Sarin

Abstract


A titrimetric method for the determination of sulphate in water samples using lead nitrate titrant andlead ion-selective electrode as end-point detector is described. A double junction reference electrode containing salt bridge of 1 M. sodium nitrate is used. The determination is carried out in 75% methanol media. The range of the method is 5 to 500 ppm of sulphate, the end-point volumes being reproducible from ± 5 to + 1% and recoveries between 90-98% are obtained in river water, well water, andmine water samples.
