And fine carbon dust is sometimes mixed in the rammed earth and the earth wall, and the carbon dust needs to collect the whole earth block during sampling. Because the carbon scraps are difficult to strip from the soil block in a whole land, the soil block (mixed with the carbon scraps) is generally directly filled into a centrifugal tube for an acid washing experiment, the carbon scraps have high weathering degree and are very easy to be crushed into powder, meanwhile, soil is also dissolved into powder, so that the carbon scraps are difficult to separate from the soil powder, and once the carbon scraps are separated unclean, the year-measuring result of the carbon scraps can be obviously influenced by the introduction of a small amount of soil.

At present, during the experiment, a suction pipe is generally used for sucking out the carbon dust so as to be separated from the soil. The method has the following problems that firstly, the carbon dust is difficult to be completely separated from the soil, and a small amount of soil is still sucked into the suction pipe in the suction process, so that the carbon dust sample to be tested contains the soil finally, and the test result has deviation; secondly, in the repeated absorption process, the carbon dust powder is increasingly crushed, so that the sample amount loss is more easily caused, and for the sample with the carbon dust content limited, the sample amount can not meet the test requirement after the repeated absorption, so that the experiment failure is caused.
