INTRODUCTION
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 damage, notify your
Dealer or the nearest Hanna office immediately. If you need additional
technical information, do not hesitate to e-mail us at
[email protected] or view our worldwide contact
list at www.hannainst.com.

SIGNIFICANCE AND USE
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 Barium Sulfate Turbidimetric Method.
Note: mg/L is equivalent to ppm (parts per million).
CHEMICAL REACTION
Sulfate is precipitated as barium sulfate by reaction with barium chloride
in acidic medium. The turbidity is proportional to the concentration of
sulfate:
INSTRUCTIONS
READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT
- Fill the plastic vessel with 50 mL of the sample, up to the mark.
- Add 1 packet of HI 38000A-0 Sulfate Reagent and swirl gently to dissolve.
- Add 2 drops of Complexing Agent and swirl to mix.
- Add two spoons of HI 38000B-0 reagent and swirl gently to mix.
- Wait for 5 minutes to allow the reaction to occur.
- Keep the test tube on a white surface and look from the top at the black spot on the bottom. Use the plastic pipette to fill the tube with the reacted sample until the black spot has completely disappeared.
- Read the concentration in mg/L (ppm) of Sulfate, in correspondence of the level of the liquid in the test tube.
Note: In the case the spot on the bottom disappears with the liquid level
under the 100 ppm mark, the sulfate concentration is higher than 100 ppm; in
the case the spot disappears with the liquid level above the 20 ppm mark, the
sulfate concentration is lower than 20 ppm.
Note: To measure Sulfate in the 100 to 10000 ppm range, use the HI 38001
Sulfate Low and High Range Test Kit.
