GOST 33587-2015 PDF

Full title and description

GOST 33587-2015 — "Уголь активированный. Стандартный метод определения адсорбционной способности при малых концентрациях адсорбируемых веществ" (English: Activated carbon. Standard method for determination of adsorptive capacity for adsorbates at trace concentrations). The standard specifies a laboratory method based on constructing adsorption isotherms to evaluate the ability of activated carbon to remove trace-level contaminants from aqueous media.

Abstract

This intergovernmental (GOST) standard defines a procedure for measuring the adsorptive capacity of activated carbon for adsorbates present at low concentrations (milligrams per litre to micrograms per litre) in water and wastewater. It is intended for characterizing both virgin and regenerated activated carbons and includes calculation of Freundlich isotherm parameters where applicable.

• Publisher: Adopted under the Interstate (GOST) system and introduced by the Federal Agency on Technical Regulating and Metrology (Rosstandart) / Interstate Council for Standardization, Metrology and Certification.
• ICS / categories: 75.160.10 (solid fuels / activated carbon applications).
• Edition / version: GOST 33587-2015 (first introduced in this series; 2015 designation, in force from 2017).
• Number of pages: Vendor/registry entries commonly list 12 pages (some copies or bookstore records indicate 16 pages when cover/annex material is included).

Scope

The standard establishes a laboratory test method to evaluate the adsorption capacity of activated carbon for trace-level adsorbates in aqueous solutions by building adsorption isotherms and determining relevant isotherm constants (for example, parameters of the Freundlich equation). It applies to both unused (fresh) and regenerated activated carbons and is intended for use where analyte concentrations are on the order of mg/L down to µg/L. The method specifies units in the SI system and notes that users are responsible for safety measures during testing.

Key topics and requirements

• Purpose: determination of adsorptive capacity of activated carbon at trace adsorbate concentrations using adsorption isotherms.
• Applicability: designed for aqueous matrices (water and wastewater) and for both virgin and regenerated carbons; suitable for analyte concentrations in mg/L to µg/L ranges.
• Analytical outputs: calculation of adsorption isotherm and extraction of Freundlich constants (K and 1/n) and related graphs.
• Test procedure elements: sample preparation, contact conditions, equilibration, analytical measurement of residual concentrations, mass-normalised adsorption (X/M) and plotting of isotherm.
• Units and reporting: SI units required; results reported with method details, conditions, and any deviations from the standard procedure.
• Normative references and equivalence: the standard references several ASTM documents for terminology and auxiliary methods; an informative annex provides correspondence notes.

Typical use and users

Primary users include analytical and environmental testing laboratories, activated carbon manufacturers and quality control departments, water and wastewater treatment designers/operators, research organizations studying adsorbent performance, and regulatory agencies setting or verifying performance criteria for adsorbents. The method is used for product characterization, quality control, research, and selection of carbons for trace contaminant removal.
