Identification method of wood activated carbon
1 Scope
This document describes the use of scanning electron microscopy and carbon 14 isotope (14C) methods for the identification of wood activated carbon and gives sample preparation, experimental
Steps and identification feature diagram.
This document is applicable to the identification of wood activated carbon and coal-based activated carbon.

in this document.
GB/T 42985 Determination of biobased content in biomass-based foam materials
3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Wood-based activated carbon
A carbonaceous adsorption material with a developed pore structure and a large specific surface area, which is made from wood raw materials through processes such as carbonization and activation.
3.2
Coal-based activated carbon
Activated carbon produced from coal.
3.3
residual biomass cell wall structure
The unique residual cell wall structure of wood activated carbon.
4 Scanning electron microscopy
4.1 Principle
The scanning electron microscope uses a concentrated electron beam with a certain energy to scan the surface of the sample, stimulate the generation of secondary electrons, and obtain the sample
Scanning image of surface morphology. Based on the unique residual biomass cell wall structure of wood activated carbon, which is different from coal-based activated carbon, wood activated carbon can be identified.
Sexual charcoal.
4.2 Instruments and Equipment
Scanning electron microscope. power supply voltage is 220 V ± 20 V, frequency is 50 Hz ± 0.5 Hz, with an independent ground wire with good grounding.
The ground resistance shall not exceed the requirements of the instrument manufacturer.
