Abstract

The invention provides a chemical detection method for the content of antimony trioxide, and relates to the field of tellurium content detection methods. The chemical detection method comprises the following steps: A, preparing raw materials; B, adding ammonium sulfite with a certain concentration into a beaker; C, heating the beaker filled with the mixture of antimony trioxide and ammonium sulfite until boiling, and then cooling the beaker; D, adding the ammonium sulfite solution into the beaker again, and cooling after heating; E, carrying out cooling and fixing the volume; F, dropwise adding a potassium permanganate standard solution into a volumetric flask; and G, calculating the content of antimony trioxide. According to the invention, a chemical redox reaction principle is utilized,the problem that the content of antimony trioxide cannot be autonomously detected in an original factory laboratory is solved, pentavalent antimony in antimony trioxide is reduced into trivalent antimony by utilizing the strong reducibility of ammonium nitrite, and therefore, the content of antimony trioxide is calculated. The whole experimental steps are simple, the authenticity and effectivenessof data are ensured, the detection cost is reduced, the working efficiency is improved, and the practicability is high.

Description

technical field [0001] The invention relates to the field of detection methods for tellurium content, in particular to a chemical detection method for antimony trioxide content. Background technique [0002] Antimony trioxide is widely used in industry, and is often used as a flame retardant synergist for polyethylene, polypropylene, polystyrene, polyvinyl chloride, nylon, engineering plastics (ABS), rubber, paint, coating, synthetic resin , paper and other materials; as a defoamer for melting glass, removing air bubbles, and as a catalyst in polyester fibers; as a passivator for heavy oil, residual oil, catalytic cracking, and catalytic reforming in petroleum; as a passivator A white pigment, which can be used in paint and other industries, and can prepare various antimonides. For the application fields with color requirements, whiteness is an important quality index of antimony trioxide products. Antimony is used as a raw material for the production of antimony trioxide....
