Abstract

The invention discloses a color developing agent for copper ion colorimetry, a copper ion colorimetric sensor, a use method and application thereof, and belongs to the technical field of heavy metal detection. The purpose is to provide a color developer for copper ion colorimetry, a sensor for copper ion colorimetry, and a method and application thereof with low cost, simple operation and no need for detection equipment. The color developer used in the copper ion colorimetric method of the present invention includes a quantum dot solution, and the quantum dot solution is an aqueous solution of quantum dots. The copper ion colorimetric sensor of the present invention comprises a housing, a reaction vessel and a light source; the light source and the reaction vessel are arranged in the housing; the reaction vessel is located at the bottom of the housing, and the light source is located above the reaction vessel; A plurality of reaction tanks are provided; the light source is a light source containing ultraviolet light with a wavelength less than 350nm. The copper ion colorimetric method sensor provided by the invention has low cost, simple operation, can perform qualitative detection without detection equipment, and has ultra-high sensitivity.

Description

technical field [0001] The invention belongs to the technical field of heavy metal detection, and in particular relates to a colorimetric sensor (colorimetric sensor) for detecting copper ions, a production method and application thereof. Background technique [0002] Copper is an element that exists widely in nature and is also an essential trace element in the human body, which plays an important role in the metabolism of the human body. When the human body does not take enough copper, it can cause deficiency diseases, but if it is taken too much, it may cause poisoning, and even cause death in severe cases. Due to the mining of copper-zinc mines, metal processing, electroplating process, machinery manufacturing, and the discharge of domestic sewage and domestic waste, the pollution caused by copper to the environment has become increasingly serious. At present, there are strict requirements on the level of copper ions in the environment at home and abroad. For example, t...
