ASTM D5919-96 (2011) rus PDF

Full title and description

St ASTM D5919-96 (2011) rus — Russian-language edition/record of ASTM D5919-96(2011): "Standard Practice for Determination of Adsorptive Capacity of Activated Carbon by a Micro‑Isotherm Technique for Adsorbates at ppb Concentrations". The original standard is published by ASTM International and the Russian edition is offered as a translation or localized product of that 2011 reapproved version.

Abstract

This practice describes a bottle‑point micro‑isotherm technique to determine the equilibrium adsorptive capacity of activated carbon for trace (ppb to low μg/L) adsorbates in water. Results yield Freundlich K and 1/n constants used to estimate carbon loading and usage rates for removal of low‑concentration organic or volatile constituents. The 2011 reapproval preserved the original 1996 designation (D5919−96) with the 2011 reapproved issue.

Scope

This practice covers the assessment of activated carbon for removal of low concentrations of adsorbable constituents from water and wastewater using a bottle‑point micro‑isotherm technique. It is applicable to virgin and reactivated carbons and may be used for constituents present in the low mg/L down to μg/L (ppb) ranges; it also allows determination of Freundlich K and 1/n constants and can be applied to volatile organic compounds when handling procedures are followed carefully. The values stated in SI units are normative.

Key topics and requirements

• Preparation and cleaning of glassware and equipment to avoid trace contamination (important for ppb‑level work).
• Sample and activated carbon preparation including particle size reduction (wet screening to ≤325 mesh where specified) and conditioning of carbon prior to testing.
• Bottle‑point micro‑isotherm technique to generate equilibrium adsorption data for calculation of Freundlich isotherm parameters (K and 1/n).
• Selection of carbon doses to produce reliable isotherm data (recommended dosages that avoid >90% or <10% removal for best data quality).
• Reporting requirements: adsorptive capacity at equilibrium, Freundlich constants, units in SI, and relevant test conditions.

Typical use and users

Used by laboratory technicians, water‑and‑wastewater treatment engineers, activated carbon manufacturers and reactivation facilities, environmental consulting laboratories, and researchers assessing carbon selection and sizing for trace contaminant removal in drinking water, process water, and effluent treatment. The method supports bench‑scale evaluation and estimation of full‑scale carbon loading.

Related standards

Commonly referenced/paired standards and practices include ASTM D1129 (terminology relating to water), D2652 (terminology relating to activated carbon), D2867 (moisture in activated carbon), D3370 (sampling water), and other ASTM guidance on activated‑carbon testing such as D3860 and the gas‑phase handbook D5160. Users often consult the related ASTM Book of Standards volume (15.01) and current reapproval notices for interrelated references.

FAQ

Q: What is this standard?

A: ASTM D5919‑96(2011) is the 2011 reapproval of ASTM D5919 (originally approved 1996): a practice describing a micro‑isotherm (bottle‑point) method to determine the adsorptive capacity of activated carbon for trace adsorbates in aqueous systems.

Q: What does it cover?

A: It covers test procedure details, sample and carbon preparation, cleaning and contamination control for ppb level testing, calculation of Freundlich K and 1/n constants, and reporting of equilibrium adsorptive capacities for use in carbon selection and loading estimates.

Q: Who typically uses it?

A: Environmental labs, water/wastewater treatment engineers, activated carbon producers and reactivation labs, and researchers evaluating carbon performance for low‑concentration contaminants.

Q: Is it current or superseded?

A: The 2011 reapproval is a historical reapproved edition of the original D5919‑96 text. ASTM records show later reapprovals and an active reapproval published in 2022 (designation D5919‑96 reapproved 2022). Users should check the most recent ASTM listing or the ASTM Digital Library for the active/reapproved status before specifying a version for regulatory or procurement purposes.

Q: Is it part of a series?

A: It is part of ASTM Committee D28 (Activated Carbon) outputs and appears in Book of Standards volume 15.01 (Refractories, Activated Carbon; Advanced Ceramics). It also cross‑refers to ASTM terminology and water sampling standards used together with adsorption testing.

Q: What are the key keywords?

A: Activated carbon, adsorption, adsorptive capacity, micro‑isotherm, bottle point, Freundlich isotherm, ppb concentrations, water treatment, D5919.
