Sulfate

Sulfate is widely present within natural waters in different concentrations. Sulfate concentration is to be kept within a strict range for drinking water, especially since this value can be high near mine drainage points. Sulfate is also rigorously tested in the production of beverages such as beer, due to its significant effect upon odor and taste.

Hanna Instruments offers a wide variety of instrumentation for measuring sulfate. Products include a titration system that can use a solid-state lead/sulfate Ion-Selective Electrode (ISE). The ISE is used as an indicator following the progress of a titration with lead perchlorate for sulfate.

In addition to titration system for measuring sulfate, Hanna offers a photometric method and chemical test kits that use reagents. The reagents contain barium chloride crystals that precipitate sulfate. For the photometric method a portable or benchtop photometer is then used to determine the sulfate concentration in a sample.

Electrodes and Probes

Lead electrodes are potentiometric devices used for the titration of sulfate with lead perchlorate. A Lead electrode may be used as an indicator to follow the progress and detect the endpoint of a precipitation titration of sulfate (with concentration >50 ppm) using lead perchlorate standard. During the titration the sensor follows the lead concentration while small additions of lead perchlorate titrant are added. The lead reacts with the sulfate ions forming a precipitate. At the stoichiometric end point, a change in mV occurs.

Chemical Test Kits

A Chemical Test Kit (CTK) is available to measure sulfate. There are two different methods to choose from. One is a turbidimetric method that has two ranges and can measure up to 100 mg/L (ppm). The other is a high range titration method that can measure up to10,000 mg/L. Both CTKs are supplied complete with all necessary items to perform the measurement.
