Brief Method Summary
|
A sample prepared according to EPA Method 200.0 is analyzed using a flame atomic absorption spectrometer. Specifications for instrument operation and preparation of standards are provided in the method. |
Scope and Application
|
This method determine vanadium by flame atomic absorption spectrometry. Sample pretreatment according to EPA Method 200.0 determines the applicability. |
Applicable Concentration Range
|
2 - 100 mg/L (optimal range); 0.8 mg/L (sensitivity). |
Interferences
|
For interferences see EPA Method 200.0. High concentrations of aluminum and titanium increase the sensitivity of vanadium. This can be controlled by adding excess aluminum to both samples and standards. |
Quality Control Requirements
|
QC requirements for drinking water procedures are provided in method 200.0 |
Sample Handling
|
Sample handling and preservation procedures are provided in EPA Method 200.0. |
Maximum Holding Time
|
6 months (MCAWW, Table 1). |
Relative Cost
|
Less than $50 |
