✦ Synopsis


Mannitol and sorbitol interfered with the orthophosphate estimation based on the formation of phosphomolybdate complex. Binding of molybdate was the cause of interference as increasing the concentration of ammonium molybdate eliminated the interference. Thus, for the estimation of orthophosphate in the presence of mannitol, the concentration of latter must be kept at below inhibitory level.
