Brief Method
Summary:

The dry residue obtained for the determination of suspended solids (method I-3765) is ignited at 550^oC for 1 h. The loss on ignition corresponds to the amount of volatile suspended solids.

Scope And
Application:

This method may be used to analyze any natural or treated water or industrial waste.

Applicable
Conc Range:

Interferences:

None of the substances commonly occurring in natural waters interfere with this method.
Because of the great variability in the nature of the compounds that can be present in the sample, particularly in samples of industrial waste, the determination can be considered only an approximation of the amount of volatile material present. Some of the volatile material may have been released during the determination of suspended solids. Moreover, ignition at 550^oC certainly volatilizes water of hydration from the hydrated salts present.

QC Requirements:

Laboratory Blanks (LB)

Sample Handling:

Container Description: 250 or 500 mL polyethylene bottle.
Handling and Treatment: Use unfiltered sample to rinse bottle.

Max Holding Time:

Relative Cost:

Less than $50
