Colourimetric determination of phosphate

Phosphate is considered to be one the most important nutrients in natural water. Although several other nutrients (eg. carbon, nitrogen, sulfur, potassium, calcium and magnesium) are required to facilitate growth of plant material, particularly algae, the phosphorus content is critical in determining the level of algal growth that the water will support.

Phosphate mining in the United States
