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
Conc 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.

QC 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.

Max Holding Time:

6 months (MCAWW, Table 1).

Sample Prep Met

200.0

Relative Cost:

Less than $50
