TEST METHODS SPECIFICATIONS
INTRODUCTION
The copper content of drinking water generally falls below 0.03 parts per
million, but copper levels as high as 1.0 part per million will give water a bitter
taste. Waters testing as high as 1.0 part per million copper have probably
been treated with a copper compound, like those used in the control of algae,
or have become contaminated from untreated industrial wastes. The addition
of copper sulfate to lakes causes an increase in the copper content of the
sediments. Acid waters and those high in free carbon dioxide may cause the
corrosion or “eating away” of copper, brass, and bronze pipes and fittings.
This corrosion results in the addition of copper into the water supply.
APPLICATION
Drinking, surface, and saline waters; domestic and industrial wastes.
RANGE
0.0 to 6.0 ppm Copper
METHOD
Cupric ions form a yellow colored chelate with diethyldithiocarbamate around
pH 9-10 in proportion to the concentration of copper in the sample.
HANDLING & PRESERVATION
Copper has a tendency to be absorbed to the surface of the sample container.
Samples should be analyzed as soon as possible after collection. If storage is
necessary, 0.5 mL of 20% hydrochloric acid per 100 mL of sample will prevent
“plating out.” However, a correction must be made to bring the reaction into
the optimum pH range.
INTERFERENCES
Bismuth, cobalt, mercurous, nickel and silver ions and chlorine (6 ppm or
greater) interfere and must be absent.

NOTE: The meter will remember the last scanned blank reading. It is not
necessary to scan a blank each time the test is performed. To use the
previous blank reading, instead of scanning a new one, scroll to Scan Sample
and proceed. For the most accurate results, the meter should be blanked
before each test and the same tube should be used for the blank and the
reacted sample.
NOTE: For the best possible results, carry a reagent blank through the
procedure. After scanning the blank, perform the test procedure on clear,
colorless, distilled or deioized water. Subtract results of regent blank from all
subsequent test results.

CALIBRATION
STANDARDS
The meter should be calibrated with copper standards. The calibration should
be done with a distilled or deionized water blank and one copper standard of
known concentration. The concentration of the calibration standard should be
similar to the expected concentration of the sample that will be tested.
CALIBRATION PROCEDURE
1. Press and briefly hold to
turn the meter on. The LaMotte
logo screen will appear for about
3 seconds and the Main Menu
will appear.
