Determination of total phosphate in phosphoric acid and phosphate fertilizers with 859 Titrotherm

Titrando family
Titrating is just intelligent dosing. With the Titrando, dosing is carried out by a Dosino and Dosing Unit mounted directly onto the reagent bottle. This means that dosing does not occupy more space than the footprint of the reagent bottle.

The Dosino is equipped with state-of-the-art mechatronics. The Dosing Unit can be replaced in no time. It is intelligent, as it is equipped with a data chip containing all the necessary data about the reagent and the Dosing Unit that is required for the titration. This information is available to the Titrando.

Each Dosing Unit has a serial and a cylinder number and is supplied with an individual certificate.
 

 
AB-314 Determination of total phosphate in phosphoric acid and phosphate fertilizers with 859 Titrotherm

Phosphate can be rapidly and easily titrated thermometrically using a standard solution of Mg2+ as titrant. The phosphate-containing solution is basified and buffered with NH3/NH4Cl solution before titration. The formation of insoluble MgNH4PO4 is exothermic. The method is a titrimetric adaptation of a classical gravimetric procedure.

This bulletin deals with the determination of phosphate in phosphoric acid and granular fertilizers such as MAP (monoammonium phosphate), DAP (diammonium phosphate) and TSP (triple superphosphate). Results are reported as percentage of P and P2O5.
