Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed by the State Forestry Administration. This standard is under the jurisdiction of the National Forest Products Standardization Technical Committee (SAC/TC558). This standard was drafted. Institute of Chemical Industry of Forest Products, Chinese Academy of Forestry. The main drafters of this standard are. Jiang Jianchun, Lu Xincheng, Sun Kang, Shu Hongnan, Deng Xianlun, Dai Weike, Zhang Yanping, Zhu Guangzhen, Chen Chao, and Jia Yujie. Wood activated carbon test method Determination of toluene adsorption rate

1 Scope

This standard specifies the method for determining the adsorption rate of toluene on wood activated carbon. This standard applies to wood granular activated carbon, but also applies to other granular activated carbon.

2 Method summary

Under the specified test conditions, the toluene-laden nitrogen stream is passed through a known mass of activated carbon sample until the sample mass no longer increases. Considered as saturated by adsorption. The toluene adsorption rate of the sample is expressed in milligrams of toluene per mg of activated carbon (mg/g).

3 Reagents

3.1 Toluene (GB/T 684). 3.2 High purity nitrogen (GB/T 8979).

4 Instruments and Equipment

4.1 Nitrogen gas flowmeter. Flow range 40mL/min~400mL/min. 4.2 Analytical balance. The amount of sense is 0.1mg. 4.3 constant temperature water bath device. temperature range RT (normal temperature) ~ 99 °C. 4.4 electric constant temperature drying oven. temperature control range RT (normal temperature) 10 °C ~ 250 °C. 4.5 Adsorption tube. Made of industrial white glass, the appearance requires no bubbles and other obvious defects. There should not be more melted glass joints Stacks and wrinkles, plugs are ground connections. The adsorption tube should be tested for airtightness before use. Inside diameter of tube body is (10±) 0.3)mm, see Figure 1. 4.6 porous gas wash bottle. 250mL. 4.7 mixed bottles. ball diameter 60mm two-ball shell type. 4.8 Temperature regulating coil. length not less than 1m. ......
