Phosphate

Phosphorus is an essential nutrient for plant growth and for living organisms. However, its increased concentration can lead to environmental problems such as excessive algae growth and reduced water quality. Phosphorus is found in natural waters and wastewater, often in the form of phosphate. Large amounts of it may be added to water by washing or using detergents.

Sources of phosphate in water

These sources are generally divided into two categories: natural and human:

1- Natural sources:

– Geological processes: They can dissolve naturally from phosphate rocks in the ground and enter groundwater or surface water.

– Natural decomposition of organic matter: The decomposition and decay of organic matter in aquatic environments can lead to an increase in its concentration.

– Rainwater: Rain can transport these compounds from the soil to surface water.

2- Human Resources:

– Domestic and Industrial Wastewater: Many industrial waste waters, such as those from some food industries, petrochemicals, and wastewater treatment plants, contain phosphates. Because these substances are the main components of many commercial detergents, they can enter rivers, lakes, and other water sources.

-Agricultural sources: The use of chemical fertilizers is a major source of these substances in water. Irrigation of plants can introduce these substances into groundwater or surface water.

Duration of sample storage

The maximum time interval between sampling and testing is 48 hours, and it should preferably be presented in a glass container.

How to measure the sample

Measurement is done using a colorimetric method and a spectrophotometer.
