1,10 - phenanthroline monohydrate has a wide range of uses in different fields. In the field of analytical chemistry, it is often used as a chelating agent. It can form stable complexes with many metal ions, such as iron, copper, and nickel. These complexes have characteristic colors and optical properties, which can be used for the qualitative and quantitative analysis of metal ions. For example, the complex formed with ferrous ions is a red - colored complex, which can be used in the spectrophotometric determination of iron.
In the field of coordination chemistry, it serves as an important ligand. The coordination compounds formed with different metal centers show diverse structures and properties, and they are of great significance for studying the structure - activity relationship of coordination compounds. In addition, in some biological research, 1,10 - phenanthroline monohydrate can also be used to study the interaction between metal ions and biomolecules because of its ability to chelate metal ions.
When using 1,10 - phenanthroline monohydrate, proper safety precautions should be taken. Wear appropriate protective equipment, such as gloves and goggles, to avoid direct contact with the skin and eyes. When preparing solutions, it is recommended to use appropriate solvents according to the requirements of the experiment. For example, if you need to prepare an ethanol solution, add the appropriate amount of 1,10 - phenanthroline monohydrate to ethanol and stir gently until completely dissolved.
When using it as a chelating agent for metal ion analysis, first, prepare a solution of 1,10 - phenanthroline monohydrate with a suitable concentration. Then, add an appropriate amount of the sample solution containing metal ions to the reagent solution. Adjust the pH of the solution if necessary to ensure the formation of stable complexes. Finally, use appropriate analytical methods, such as spectrophotometry, for detection.
Case 1: Iron determination in water samples. A water treatment plant needs to determine the iron content in raw water. They first prepared a 0.1 mol/L solution of 1,10 - phenanthroline monohydrate in ethanol. Then, they took a certain volume of the water sample, adjusted the pH of the sample to about 3 - 4 with buffer solution, and added an appropriate amount of the 1,10 - phenanthroline monohydrate solution. After reacting for a certain period of time, they used a spectrophotometer to measure the absorbance of the solution at a specific wavelength. By comparing with the standard curve, they accurately determined the iron content in the water sample, which provided an important basis for subsequent water treatment processes.
Case 2: Synthesis of a new coordination compound. A research group in a university was engaged in the synthesis of a new copper - based coordination compound. They used 1,10 - phenanthroline monohydrate as a ligand. They mixed an aqueous solution of copper(II) sulfate with a solution of 1,10 - phenanthroline monohydrate in ethanol under appropriate reaction conditions. After a series of reactions and purification steps, they successfully synthesized a new copper - 1,10 - phenanthroline coordination compound. The study of this new compound's structure and properties provided new ideas for the development of materials science.
