DearCustomer,
Thank you for choosing a Hanna Product.

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);
• 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.

Manganese
Low Range
Test Kit
ISTR38042 10/00 PRINTED IN ITALY
Manganese is not present in natural waters but it is found
in various salts and minerals, frequently associated with
iron compounds. Manganese salts are used as fertilizer
additives, in ferroalloys (in 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.

• 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 20 mL of sample (up to the
mark).
• Insert one of the vials into the left hand opening of the
checker disc. This is the blank.
• Add to the other
vial 1 packet of
HI 93709A-0 re-
agent.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
seconds 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 checker disc.
• Holdthechecker disc so that
alight sourceilluminatesthe
samples from the top.
• Keep the checker disc at a
distance of 30-40 cm (12-
16") to match the color.
Rotatethe discwhilelooking
at the color test windows and stop when you find the
color match. Read the value in the result window and
divide it by 3 to obtain 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).Intenselycolored sampleswillmakethecolor

before performing the test. Suspended 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.
