HI 3833

Phosphate

Test Kit

ISTR3833C 12/99 PRINTED IN ITALY

Phosphates are widely introduced into the environment from
such sources as agricultural fertilizers, cleaning and laun-
dering products, boiler water conditioners, and drinking
water treatment aids.
At high levels, phosphates stimulate the growth of photo-
synthetic organisms which may contribute to eutrophication
of lakes, rivers, and ponds. This makes it important to
monitor and control phosphate discharges into the environ-

ment.
Phosphates can be classified as ortho, condensed or organi-

cally bound. As with existing test kits on the market, the
Hanna Phosphate Test Kit will only determine ortho phos-
phate levels.
NOTE: mg/L is equivalent to ppm (parts per million).

SIGNIFICANCE AND USE

Dear Customer,
Thank you for choosing a Hanna Product.
Please read this instruction manual carefully before using
the chemical test kit. It will provide you with the necessary
information for correct use of the kit.
Remove the chemical test kit from the packing material and
examine it carefully to make sure that no damage has
occurred during shipping. If there is any noticeable dam-
age, notify your Dealer or the nearest Hanna office
immediately.
Each kit is supplied with:

• 1 beaker (20 mL);
• 1 color comparator cube;
• HI 3833-0 powder reagent (100 pcs).

Note: Any damaged or defective item must be returned in

its original packing materials.

READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT
• Remove the cap from the plastic

vessel. Rinse the plastic vessel with
water sample, fill it to 10 mL
mark.

• Add 1 packet of reagent HI 3833-0.

• Replace the cap and mix solution

until solids dissolve.

• Remove the cap and transfer the solution into the color

comparator cube. Let set for 1 minute.

• Determine which color matches the solution

in the vessel, and record the results as

mg/L (or ppm) PO

INSTRUCTIONS

The orthosphosphate level in mg/L (or ppm) is determined

by a colorimetric method. Ammonium molybdate and potas-
sium antimonyl tartrate react in acid medium with
orthophosphate to form a phosphomolybdate complex, that
is reduced to intensely colored molybdenum blue by ascor-
bic acid. The color intensity of the solution determines the
phosphate concentration.
