DearCustomer,
Thank you for choosing a Hanna Product.
Please read the instruction sheet carefully before using the
test kit. It will provide you with the necessary information
for correct use of the kit. If you need additional information,
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:
•HI93709A-0CitrateBufferReagent,packets(100pcs);
•HI93709B-0SodiumPeriodate Reagent, packets (100
pcs);
Deionized Water, 2 bottles (2x230 mL);
• 1 checker disc (containing a mirror, a mirror holder
and the 38072 disc);
• 2 glass vials with caps;
•1 plastic pipette (3 mL).
Note: Any damaged or defective item must be returned in
its original packing materials.
HI 38072
Manganese
Test Kit for
Irrigation Water
ISTR38072 02/00 PRINTED IN ITALY
Manganese is not occurring in natural waters but it is
found in various salts and minerals, frequently associated
withiron compounds.Manganesesalts areusedas fertilizer's
additives, in ferroalloys (in the steel manufacture), in non-
ferrous alloys as it improves their corrosion resistance and
hardness.
Manganese is not considered to be toxic to man and
aquatic life and it is ingested as a trace nutrient, both in
food and water. Nonetheless manganese has been limited
in drinking water since it causes tenacious stains to laundry
and because it produces objectionable tastes in beverages.
Manganese is commonly found in domestic wastewater,
industrial effluents and receiving streams.
Note: mg/L is equivalent to ppm (parts per million).

The reaction between manganese and reagents causes a
violet tint in the sample which is proportional to the
manganese concentration.
READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT
• Verify that the mirror, its holder and the disc are pre-
installed in the checker disc. If not, install them as
shown in the figure.

• Usingthe plasticpipette,fill each glass
vial with 7.5 mL of sample (up to the
mark).
• Insert one of them into the left hand
opening of the checker disc. This is the
blank.
• Add to the other vial
Deionized Water up
to the 10 mL mark.
Replace the cap and
shake to mix.
• Remove the cap
and add 1 packet
of HI 93709A-0
reagent. Replace
the cap and swirl
to mix.
• Remove the cap
and add 1 packet
ofHI93709B-0re-
agent. Replace the
cap and swirl to
mix.
• Wait for 1 minute and 30 sec-
onds to allow reaction to occur.
This is the reacted sample.
• Remove the cap and insert
the reacted sample into the
right hand opening of the
checkerdisc.
• Holdthechecker disc so that
alight sourceilluminatesthe
samples from the top.
• Keep the checker disc at a distance of 30-40 cm (12-
16") from the eyes to match the color. Rotate the disc
while looking at the color test windows and stop when
you find the color match. Read the value in the result
window directly in mg/L (or ppm) of Manganese.
For best results: Perform the reading three times and
take the average value (divide by 3 the sum of the
three numbers). Intensely colored samples will make
the color matching difficult and they should be
adequately treated before performing the test. Sus-
pended matter in large amounts should be removed
by prior filtration.
Caution: Ultraviolet radiation may cause fading of colors.
When not in use, keep the disc protected from light,
in a cool and dry place.
Interferences:Calcium above 700 ppm, magnesium above
100000 ppm, chloride above 7000 ppm, iron above
5 ppm.
