SAMPLE
HANDLING &
PRESERVATION:
Copper has a tendency to be adsorbed 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:
High concentrations of oxidizing agents, calcium, and
magnesium interfere. Silver can also interfere.
