Wood activated carbon test method Formaldehyde adsorption rate determination

1 Scope

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

2 method summary

Under the specified test conditions, a formaldehyde-laden nitrogen stream is passed through a sample of activated carbon of known mass until the sample mass does not increase, As adsorption saturation. The formaldehyde adsorption rate of the sample is expressed in milligrams per gram of formaldehyde adsorbed formaldehyde (mg/g).

3 reagent

3.1 Formaldehyde solution (GB/T 685). Analytical purity, formaldehyde content 37.0% ~ 40.0%. 3.2 high purity nitrogen (GB/T 8979).

4 instruments and equipment

4.1 Nitrogen gas flow meter. Flow range 60mL/min ~ 600mL/min. 4.2 Analytical Balance. Sense of 0.1mg. 4.3 constant temperature water bath temperature control range RT (room temperature) ~ 99 ℃. 4.4 electric oven, temperature range RT (room temperature) 10 ℃ ~ 250 ℃. 4.5 Adsorption tube made of industrial white glass, the appearance of no bubbles and other obvious defects. Glass welding should not have more melting Then heap and crease, plug for the grinding mouth connection. Adsorption tube must be tested for airtightness before use. Inside the tube scale inside diameter (10 ± 0.3) mm, see Figure 1. 4.6 porous gas bottle. Capacity of 250mL. 4.7 mixed bottle. Ball diameter 60mm two ball shell-type. 4.8 temperature control with a snake tube. Length of not less than 1m. ......
