Problems solved by technology

[0004] Although there are more and more fluorescent probes used in the detection of silver ions, there are still many shortcomings, such as poor detection limit, cumbersome synthesis procedures, interference from other transition metal ions, long response time, and the use of organic solvents.
Moreover, most silver ion fluorescent probes are mainly composed of rhodamines and pyrenes, which have great environmental hazards during production and application.

Embodiment 1

[0052] Preparation of copper nanoparticles solution

[0053] Using polyvinylpyrrolidone as a protective agent, 2-mercaptobenzothiazole as a stabilizer, and hydrazine hydrate as a reducing agent, a new method for preparing orange-red fluorescent copper nanoparticles, the reaction schematic diagram is as follows figure 1 Shown:

[0054] (1) Accurately weigh copper chloride, dissolve and prepare CuCl with a concentration of 1.0mM in ultrapure water 2 Aqueous solution; accurately weigh 2-mercaptobenzothiazole, dissolve it with 1.0M NaOH solution to prepare 10.0mM 2-mercaptobenzothiazole solution; accurately weigh polyvinylpyrrolidone, dissolve it with ultrapure water to obtain a concentration of 0.07mM Pipette 1.0mL of copper chloride solution, 10.0mL of polyvinylpyrrolidone solution, and 5.0mL of 2-mercaptobenzothiazole solution in a clean and dry 25.0mL colorimetric tube.

[0055] (2) Add 0.4 mL of hydrazine hydrate stock solution to the solution in step (1), then set the volu...

Embodiment 2

[0067] The technical solution of this embodiment is the same as that of Example 1, except that 2.0 mL of polyvinylpyrrolidone solution is added in step (2), and the concentration of polyvinylpyrrolidone in the solution system is adjusted to 5.6 μM.

Embodiment 3

[0069] The technical solution of this embodiment is the same as that of Embodiment 1, except that 6.0 mL of polyvinylpyrrolidone solution is added in step (2), and the concentration of polyvinylpyrrolidone in the solution system is adjusted to 16.8 μM.

Abstract

The invention discloses copper nanoparticle solution as well as a preparation method and application thereof. The preparation method of the copper nanoparticle solution comprises the following steps that aqueous solutions of copper chloride, 2-mercaptobenzothiazole and polyvinylpyrrolidone are respectively prepared, then the aqueous solutions are mixed and added with hydrazine hydrate, and finallythe solution is stand at 10-20 DEG C to obtain the strong orange fluorescence emission copper nanoparticle solution. The prepared copper nanoparticle solution probe is high in stability, can be usedfor detecting silver ions and is applied to silver ion detection test paper, and detection of the silver ions is visualized. The copper nanoparticle solution can also be used for pattern dyeing and manufacturing.

Description

technical field [0001] The invention relates to the technical field of metal nanoparticles, in particular to a copper nanoparticle solution and its preparation method and application. Background technique [0002] Silver ions are widely used in production, life, medicine and other aspects due to their antibacterial, disinfection and anti-inflammatory properties, such as silver ion washing machines, silver ion refrigerators, etc. However, excessive use of silver ions will cause life-threatening and serious pollution to the human body and the environment. For example: excessive intake and long-term accumulation of silver ions will lead to insoluble deposits in the eyes and skin, and will also inactivate the normal function of thiol enzymes, human anemia, growth retardation, heart enlargement and other degenerative changes, which can also make microorganisms Death by suffocation, toxicity to certain bacteria, viruses, algae and fungi, and pollution of drinking water in the env...
