SIGNIFICANCE AND USESIGNIFICANCE AND USE
Phosphates are widely introduced into the environment from
such sources as agricultural fertilizers, cleaning and laundering products, boiler water conditioners, and drinking
water treatment aids.
At high levels, phosphates stimulate the growth of photosynthetic organisms which may contribute to eutrophication
of lakes, rivers, and ponds. This makes it important to
monitor and control phosphate discharges into the environment.
Phosphates can be classified as ortho, condensed or organically bound. As with existing test kits on the market, the
Hanna Phosphate Test Kit will only determine ortho phosphate levels.
NOTE: mg/L is equivalent to ppm (parts per million).

The orthosphosphate level in mg/L (or ppm) is determined
by a colorimetric method. Ammonium molybdate and potassium antimonyl tartrate react in acid medium with
orthophosphate to form a phosphomolybdate complex, that
is reduced to intensely colored molybdenum blue by ascorbic acid. The color intensity of the solution determines the
phosphate concentration.
