Brief Method Summary
|
The residue obtained from the determination of total, filterable or non-filterable residue is ignited at 550oC in a muffle furnace. The loss of weight on ignition is reported as mg/L volatile residue. |
|
Scope and Application
|
This method determines the weight of solid material combustible at 550oC. The test is useful in obtaining a rough approximation of the amount of organic matter present in the solid fraction of sewage, activated sludge, industrial wastes, or bottom sediments. |

Applicable Concentration Range
|
Not Available. |
|
Interferences
|
None. |

|
None. |
|
Sample Handling
|
Preservation of the sample is not practical; analysis should begin as soon as possible. Refrigeration or icing to 4oC is recommended. |
|
Maximum Holding Time
|
7 days (MCAWW, Table 1). |
|
Relative Cost
|
Less than $50 |
|
Sample Preparation Methods
