The invention belongs to the technical field of nanometer materials, and discloses a preparation method of nanometer zinc oxide and nanometer zinc sulfide. The preparation method includes the following steps: acidolysis zinc-containing substances, reacting zinc sulfate and soluble carbonate to prepare nano-zinc oxide; then reacting barium sulfide and sulfate to prepare nano-barium sulfate; React with zinc sulfate to prepare nano-zinc sulfide, and reuse the sulfate produced in the preparation. The invention can simultaneously prepare nanometer zinc oxide, nanometer barium sulfate and nanometer zinc sulfide, wherein, the purity of nanometer zinc oxide is greater than 95%, and the yield is greater than 90%; the purity of nanometer barium sulfate is greater than 95%, and the yield is greater than 90%, The purity of the nano zinc sulfide is greater than 99%, and the yield is greater than 90%. In the preparation method, by cyclically using sulfate, zero discharge of waste salt and waste water is realized, production cost is reduced, and it is a green full-cycle preparation method. |
