The invention discloses a method for determining the content of titanium dioxide in livestock and poultry manure, which comprises the following steps: putting a livestock and poultry manure powder sample into a digestion container, and adding a digestion solution for digestion to obtain a sample digestion solution; wherein the digestion solution comprises nitric acid, hydrofluoric acid and sulfuric acid; and measuring the titanium element content of the sample digestion solution, and calculating to obtain the content of titanium dioxide. According to the technical scheme provided by the method for determining the content of titanium dioxide in the livestock and poultry manure, the livestock and poultry manure with complex components can be effectively digested through a digestion system formed by synergistic cooperation of nitric acid, sulfuric acid and hydrofluoric acid, digestion is thorough, digestion efficiency is high, and therefore the content of titanium dioxide in the livestock and poultry manure can
