Dear Customer,
Thank you for choosing a Hanna Product.
Please read the instructions 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.

• HI 38001B-0 HR Sulfate Reagent, 1 bottle (100mL);
• HI 38001C-0 Sulfate Reagent, 1 bottle with dropper
(10 mL);
• Complexing Agent, 1 bottle with dropper (20 mL);
• Sulfate Solution, 1 bottle (30 mL);
• 2 plastic vessels (50 mL);
• 2 syringes (1 mL).
Note:
Any damaged or defective item must be returned in
its original packing materials.

Sulfate is largely present in natural waters in a wide range
of concentrations. It is not toxic but has to be kept below a
certain threshold to prevent it from creating an unpleasant
taste in water. The concentrations are particularly higher
close to mine run-off water. Sulfate is extensively used as a
nutrient in agriculture.
The procedure for determining sulfate is a modification of
the Determination of Sulfate by Sulfonazo III.
Note:
mg/L is equivalent to ppm (parts per million).

Low Range - 100-1000 mg/L Sulfate
• Remove the caps from the plastic
vessels. Fill one vessel with 15 mL of
the sample, up to the mark, and,
when you perform the test for the
first time, fill the other plastic vessel
with 15 mL of Sulfate Solution. This
will help you in identifying the final
color of your sample.

• Add 1 packet of HI
38001A-0 Sulfate
Reagent to each ves-
sel, replace the cap
and swirl gently to
dissolve.
• Add 2 drops of
Complexing Agent to
each vessel and swirl
to mix.
• Add 1 drop of HI
38001C-0 Sulfate Re-
agent to each vessel
and mix by carefully
swirling in tight
circles. The solutions
will turn violet. Re-
place the caps.
• Insert syringe tip into
HI 38001B-0 LR ti-
tration solution and
pull the plunger out
until the lower edge
of the black plunger
seal is on the first
graduation mark
(zero) on the syringe
body.
• Place the syringe tip into the
cap port of the plastic vessel
containing the Sulfate Solu-
tion and, while swirling, add
0.5 mL of HI 38001B-0 LR to
see clearly the color change
from violet to blue. This is
your color change reference.
• Refill the syringe with HI 38001B-0 LR reagent and
place the syringe tip into the cap port of the plastic
vessel containing the sample. Add slowly the titration
solution drop by drop, swirling and waiting a few
Sulfate is determined via a titrimetric method. The reaction
end point is indicated by the change in color of the solution
from violet to blue.
The chemicals contained in this kit may be hazardous if
improperly handled. Read Health and Safety Data Sheet
before performing this test.

seconds after each drop.
Note:
The solution becomes turbid but this
reaction will not affect the result.
• Continue adding the titration solution
until the solution in the plastic vessel
changes from violet to blue.
• Read off the milliliters of titration solution
from the syringe scale and multiply by 1000 to obtain
mg/L (ppm) of Sulfate.
• If the solution will not turn blue, the sample contains
more than 1000 mg/L of sulfate.
High Range - 1000-10000 mg/L Sulfate
• Remove the cap from the plastic vessel and fill it with 15
mL of the sample, up to the mark.
• Proceed with the test as described
before, using HI 38001B-0 HR as
titration solution instead of HI 38001B-
0 LR (fill the other syringe to perform this test).
• Read off the milliliters of titration solution from the
syringe scale and multiply by 10000 to obtain mg/L
(ppm) of Sulfate.
Note:
To measure Sulfate in the 20 to 100 ppm range, use
the
HI 38000
Sulfate Test Kit.
