1.1 本规程涵盖活性炭吸附能力的测定，以去除水和废水中的不良成分。它可用于评估活性炭或再活化炭的吸附能力。 1.2 除非采取特殊预防措施以减少样品制备和分析过程中的损失，否则不建议采用这种做法。 1.3 建议使用本规程确定活性炭在以下应用中的吸附容量，但不限于这些应用: 1.3.1 去除染料厂废水中的颜色， 1.3.2 去除饮用水中的味道或气味成分，或两者兼而有之， 1.3.3 去除水中的有毒物质， 1.3.4 去除水中的表面活性剂， 1.3.5 去除BOD 5. 来自生活废水，以及 1.3.6 从工业废水中去除TOC。 1.4 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 当活性炭被视为水处理中的吸附剂时，使用这种做法。 由于颗粒活性炭和粉末活性炭都可以在市场上买到，因此需要一种标准做法来确保在相同的测试条件下对活性炭进行评估。使用规定粒度的碳，以确保使用相同的试验条件。该练习通常在20岁时进行 °C；但是，可以使用并记录其他温度。

1.1 This practice covers the determination of the adsorptive capacity of activated carbon to remove undesirable constituents from water and waste water. It can be used to evaluate the adsorptive capacity of activated or reactivated carbon. 1.2 This practice is not recommended unless special precautions are taken to reduce loss during sample preparation and analysis. 1.3 This practice is recommended to determine the adsorptive capacity of activated carbon for the following applications, but is not limited to these applications: 1.3.1 Removal of color from dye mill waste water, 1.3.2 Removal of taste or odor constituents, or both, from potable waters, 1.3.3 Removal of toxicants from water, 1.3.4 Removal of surface-active agents from water, 1.3.5 Removal of BOD 5 from sanitary waste waters, and 1.3.6 Removal of TOC from industrial waste waters. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This practice is used when activated carbon is considered as an adsorbent in treating water. Since both granular and powdered activated carbons are commercially available, a standard practice is needed to ensure that the activated carbons are evaluated under the same test conditions. Specified particle size carbon is to be used to ensure that the same test conditions are used. The practice is generally performed at 20 °C; however, other temperatures may be used and noted.
