Copper-PAN complex (CU-EDTA PAN) is a complex of copper ions (Cu2 +) complexed with polyacrylamide (PAN) and ethylenediaminetetraacetic acid (EDTA).
Nature:
1. Appearance: The copper-PAN complex appears as a blue or blue-green solid.
2. Solubility: It can be dissolved in water and some organic solvents, such as methanol and acetic acid.
3. Stability: The complex has good thermal stability and chemical stability.
4. easy separation: copper-PAN complex is easy to be separated from the solution by filtration or precipitation.
Use:
1. Analytical Chemistry: Copper-PAN complex can be used for the quantitative analysis, detection and determination of copper ions.
2. Polymer materials: Due to its good dyeing and oxidation resistance, copper-PAN complexes are often used in the production of dyes and pigments, and the dyeing of textiles and coatings.
Preparation Method:
1. Copper-PAN complex can usually be formed by reacting copper salt (such as copper sulfate) and PAN in aqueous solution, and then adding EDTA solution.
2. The preparation process needs to control the reaction conditions (such as temperature and pH) to ensure the formation of the complex.
Safety Information:
1. Copper-PAN complex is relatively safe under normal circumstances, but the following matters still need to be paid attention:
2. avoid contact with skin and eyes, such as accidental contact should immediately rinse with plenty of water.
3. avoid inhalation of dust, operation should wear appropriate protective equipment.
4. Storage should avoid contact with oxidants and flammable substances.
5. in case of accidental intake or other accidents, please seek medical attention in time.
