|
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 Concentration Range
|

|
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. |
