| Abstract: | The present invention relates to zone heating and smelting and molecular diffusion process to purify solid matter, such as yellow phosphorus via eliminating As. By means of zone heating and smelting and molecular diffusion, As content in yellow phosphorus is lowered while lowering the content of other impurities. In addition, no any pollution will be produced in the operation. |
