The invention discloses a preparing method of high-purity carbon dioxide. In the method, shell and acid are adopted as raw material to react according to the ratio of 1:2 to prepare carbon dioxide in one step, and the reaction ionic equation is as follows: CaCO3+2H+->Ca2++CO2+H2O. The invention has the effect and benefit of simple process flow, low cost and high purity of produced carbon dioxide. If the shell and the acid (which can also be waste acid) react, not only high-purity carbon dioxide can be produced, and by-product calcium salt can be obtained as well, which further creates economic value and solves the problem of shell pollution. The invention takes the shell as raw material to produce high-purity carbon dioxide. Because the shell contains a large amount of calcium carbonate and a small amount of impurity, the produced carbon dioxide has high purity; in addition, the shell belongs to waste, so that the use of the shell belongs to waste recycling; the produced product has low price, greatly reduces environment pollution caused by wasted shells and has important environment protection meaning.
