Test methods for wood activated carbon - Part 1.Determination of conductivity of water extract
1 Scope
This document specifies a method for the determination of the conductivity of activated carbon water extracts.
This document applies to wood-based activated carbon and also applies to coal-based activated carbon.
2 Normative references
The contents of the following documents constitute the essential provisions of this document through normative references in the text. Among them, dated references
For documents, only the version corresponding to the date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to
this document.

3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
The mass of activated carbon per unit volume of tannic acid solution.
Note. The unit is milligrams per liter (mg/L).
3.2
Tannic acid adsorption value tannicvalue
The concentration of activated carbon required to reduce the concentration of tannic acid from 20 mg/L to 2 mg/L.
Note. The unit is milligrams per liter (mg/L).
4 principles
Activated carbon contains impurities such as soluble inorganic salts, which can cause changes in the conductivity of aqueous solutions after being dissolved in water. By testing the changes in conductivity
It reflects the content of soluble inorganic salts in activated carbon.
5 Reagents or Materials
