ASTM D2330-02<\/h3>\n

Historical Standard: Standard Test Method for Methylene Blue Active Substances (Withdrawn 2011)<\/h4>\n
\n

ASTM D2330<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers the determination of compounds that react with methylene blue under the conditions specified in the test procedure. They are referred to as methylene blue active substances (MBAS), and are calculated and reported in terms of the reference material, linear alkyl benzene sulfonate, LAS.<\/p>\n

1.2 This test method is applicable for determining MBAS in water and wastewater. It is the user’s responsibility to ensure the validity of this test method for waters of untested matrices.<\/p>\n

1.3 This test method is a simple, rapid, control procedure suitable for monitoring the effectiveness of a biodegradation or other linear alkyl benzene sulfonate (LAS) removal process. For greater specificity and interference removal, the pretreatment procedure in should be used. Data derived without the pretreatment procedure should be interpreted with care. This test method is applicable in the range from 0.03 to 1.5 mg\/L for a 100-mL sample.<\/p>\n

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/i> For a specific hazard statement, see 8.3.<\/p>\n
