Drying method is generally used, that is, the carbon sample into a pre-dried and constant weight with a lid weighing bottle, accurately weighed 3 to 5 grams of activated carbon samples, and then placed in an electric oven, at (150 ± 5) ℃ temperature drying at constant temperature above 2h to constant weight, and then placed in a desiccator, cooled to room temperature and weighed. The moisture content is expressed as a percentage of the mass of the lost sample.

Measurement, according to the technical requirements of the product, select a corresponding set of standard sieve, according to the size of the sieve from the top down and placed on the sieve shaker, weighed 100g of activated carbon sample sieve sieve placed in the upper sieve, Start the vibration sieve machine vibration for 10 minutes, and then in turn remove the layers of sieve, collect and weigh the samples on each sieve layer, calculate the sample retained in the sieve layer on the quality of the sample mass percentage, get activated carbon particle size distributed.
5, packing density
Since the adsorption of activated carbon for gas phase adsorption is exothermic, the carbon layer may ignite if sufficient thermal conductivity of the carbon layer is not considered. Therefore, the detection of activated carbon ignition point is necessary. In the air flow at a constant heating rate of heating the sample, with the temperature rise, the carbon-like temperature will suddenly exceed the temperature of the air into the charcoal layer, the temperature at this point is the ignition point of activated carbon.
7, floating rate
The dried and cooled 20g sample placed in 500ml beaker, add 200ml of distilled water at room temperature and stirred 2 times, allowed to stand for 10min, the sample floating on the water removed after drying and weighed to calculate the floating rate.
