Standard Test Methods for Determining the Organic Treat Loading of Organophilic Clay

Importancia y uso:

5.1 This standard test method is intended as an index test to determine the organic treat loading of organophilic clay. This standard test method can be used for manufacturing quality control and construction quality assurance material evaluation.

5.2 The percent organic treat loading of organophilic clay is a relative indicator of its adsorptive capacity. Organophilic clay is used for remediation of contaminated sediment, soil, and groundwater.

5.3 The two test methods denote different devices, a muffle furnace and a thermal gravimetric analyzer. The thermal gravimetric analyzer may be programmed to reach a higher temperature than the muffle furnace, but the organic matter will be burnt off at 750 °C.

Note 3: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.
