Determination of Sulfate (SM 4500 SO3-2 Method)

The SM 4500-SO3-E method, which includes a test method for the determination of sulfate, has been developed within the scope of the National Environmental Methods Index (NEMI), which creates a database of environmental methods, protocols, statistical and analytical methods and procedures and develops standard methods.Migrants.

Sulfate ions are formed in sulphate-treated boilers and boiler feed waters for dissolved oxygen control, in natural waters or wastewater as a result of industrial pollution, and in treatment plant wastewater dechlorinated with sulfur dioxide. Excess sulfide ions in boiler water is harmful because it lowers the pH value of the water and increases corrosion. The control of sulfide ions in wastewater treatment and discharge is important in terms of environmental conditions, especially due to its toxicity to fish and other aquatic organisms and its rapid oxygen demand.

The iodometric titration method is considered suitable for relatively clean waters with concentrations above 2 mg/L sulfur trioxide. Colorimetric determination of phenanthroline following evolution of sulfide from the sample matrix as sulfur dioxide is preferred for low levels of sulfite.

This standard provides both titrimetric and spectrometric methods for sulfate determination.

In the tests and analyzes carried out in our institution, which has a wide range of technological equipment, trained and experienced staff and applies the most modern methods, national and international standards and legal regulations in force are complied with. Among the numerous tests performed in this context, there are also sulfate determination (SM 4500-SO3 E method) services.
