Brief Method
Summary:

Nickel is determined by atomic absorption spectrometry by direct aspiration of the sample into an air-acetylene flame without preconcentration or pretreatment.

Scope And
Application:

Suspended recoverable nickel is calculated by subtracting dissolved nickel (I-1499) from total recoverable nickel (I-3499).

Applicable
Conc Range:

N/A

Interferences:

Individual concentrations of sodium (9,000 mg/L), potassium (9,000 mg/L), calcium (4,000 mg/L), magnesium (4,000 mg/L), sulfate (9,000 mg/L), and cadmium, lead, copper, zinc, cobalt, and chromium (10,000 ug/L each) do not interfere. Higher concentrations of each constituent were not investigated.

QC Requirements:

No QC requirements. Suspended recoverable nickel is a calculation.

Sample Handling:

N/A

Max Holding Time:

Relative Cost:

Less than $50
