Abstract

The invention discloses a method for detecting potassium dichromate by utilizing a graphene quantum dot probe. The method is characterized by comprising the following steps: (1) establishing a linear relationship: preparing a standard solution of graphene quantum dot and potassium dichromate solution, and obtaining the linear relation between the fluorescent intensity of the graphene quantum dot and the concentration of the potassium dichromate through the fluorescent spectra; (2) detecting: detecting the fluorescent intensity of the to-be-detected potassium dichromate solution, and determining the content of the potassium dichromate in the to-be-detected potassium dichromate solution according to the linear relation. The method is easy to operate, rapid in detection, high in sensitivity and good in selectivity, has the characteristics of high sensitivity and high selectivity when potassium dichromate in a mixed sample is detected and is promising in application prospect.

Description

technical field [0001] The invention belongs to the technical field of chemical detection, and in particular relates to a method for detecting potassium dichromate by using a graphene quantum dot probe. Background technique [0002] Potassium dichromate is a toxic and carcinogenic strong oxidizing agent, it is orange-red solid at room temperature. It is classified as a first-class carcinogen by the International Agency for Research on Cancer, and it is a strong oxidant, which is widely used in laboratories and industries. Potassium dichromate is mainly used in the chemical industry as the main raw material for the production of chromium salt products such as chromium trioxide; in the match industry, it is used as an oxidant for making matchheads; in the enamel industry, it is used to make enamel powder to make enamel green; It is used as a coloring agent in the industry; as a mordant in the printing and dyeing industry; as an oxidizing agent in the fragrance industry; in ad...
