木質(zhì)活性炭鑒別方法

1范圍

本文件描述了掃描電鏡法和碳14同位素（14C）法用于木質(zhì)活性炭鑒別，并給出了樣品制備、試驗

步驟以及鑒別特征圖。

本文件適用于木質(zhì)活性炭與煤質(zhì)活性炭的鑒別。

2規(guī)范性引用文件

下列文件中的內(nèi)容通過文中的規(guī)范性引用而構(gòu)成本文件必不可少的條款。其中，注日期的引用文

件，僅該日期對應(yīng)的版本適用于本文件；不注日期的引用文件，其最新版本（包括所有的修改單）適用

于本文件。

GB/T42985生物質(zhì)基泡沫材料中生物基含量檢測方法

3術(shù)語和定義

下列術(shù)語和定義適用于本文件。

3.1

木質(zhì)活性炭wood-basedactivatedcarbon

由木質(zhì)原料經(jīng)炭化、活化等工藝制成的孔隙結(jié)構(gòu)發(fā)達、較大比表面積的碳質(zhì)吸附材料。

3.2

煤質(zhì)活性炭coal-basedactivatedcarbon

以煤為原料生產(chǎn)的活性炭。

3.3

殘留生物質(zhì)細胞壁結(jié)構(gòu)residualbiomasscellwallstructure

木質(zhì)活性炭特有的殘留細胞壁結(jié)構(gòu)。

4掃描電鏡法

4.1原理

掃描電鏡法利用被聚集的、具有一定能量的電子束在樣品表面掃描，激發(fā)產(chǎn)生二次電子，獲得樣品

表面形貌的掃描圖像。依據(jù)木質(zhì)活性炭區(qū)別于煤質(zhì)活性炭獨有的殘留生物質(zhì)細胞壁結(jié)構(gòu)，來鑒別木質(zhì)活

性炭
