Determination of Phosphate/Phosphate Phosphorus (SM 4500-PD Method)

Determination of Phosphate/Phosphate Phosphorus (SM 4500-PD Method)

SM 4500-PD method including a test method for the determination of phosphate/phosphate phosphorus under the National Environmental Methods Index (NEMI) developed. Phosphorus is found almost exclusively as phosphate in natural waters and wastewater. These are classified as orthophosphates, condensed phosphates and organically bound phosphates. It occurs in solution, in particles or debris, or in aquatic organisms.

These phosphate forms arise from a variety of sources. Small amounts of orthophosphate or certain concentrated phosphates are added to some water sources during industrial activities. Larger amounts of the same compounds are added during laundry or other cleaning because these materials are the main ingredients in many commercial cleaning preparations.

Phosphates are widely used in the treatment of boiler water. Orthophosphates applied as fertilizer to agricultural or residential cultivated lands are transported to surface waters. Organic phosphates are primarily formed by biological processes. They end up in sewers with bodily wastes and food residues, and may also be formed from orthophosphates or dewatering biota in biological treatment processes.

Phosphorus is essential for the growth of organisms and is the nutrient that limits the primary productivity of a water body. Phosphates also occur in bottom sediments and biological sludges, both in precipitated inorganic forms and incorporated into organic compounds.

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 phosphate/phosphate phosphorus determination (SM 4500-PD method) services.
