Abstract:

Phosphorus, in the form of organic or inorganic phosphate, is an important and widely distributed element in nature. Excessive phosphorus causes water to entrophicate. Most of the commonly used methods for the determination of inorganic phosphate in water are based on spectrophotometric measurement of the phosphomolybdate or phosphomolyb-dovanadate, Among the fluorescence quenching methods using metal chelates, the aluminium-morin system was found to be the most suitable for determining phosphate^[1].
