Analytical Chemistry Lab
Machine-translated · View original
A lab that turns the ability of molecules to recognize other molecules into techniques for separating and measuring substances.
AboutAbout the lab
How molecules recognize other molecules
The Analytical Chemistry Lab studies methodologies for separating and analyzing substances.
The ability of a molecule to distinguish a partner by its size, shape, and electron configuration, and to select it for reaction, is called molecular recognition.
For functional substances such as ionic liquids and supramolecular complexes, the lab investigates in detail the reactions in solution and the recognition ability.
Based on its findings, the lab enhances reaction selectivity, creates new substances, and applies them to separation and analytical methods.
Key terms
- Molecular recognition
- The process by which a molecule distinguishes and selects a partner molecule or ion based on differences in size, shape, and electron configuration.
- Ionic liquid
- A salt that is liquid at room temperature. It is highly safe and well suited to the environment.
- Solvent extraction
- A method that uses two immiscible liquids to transfer only the target component into one of them and extract it.
ResearchResearch themes
Analytical chemistry is a discipline that explores methodologies for separating and analyzing substances. The lab studies, from both fundamental and applied perspectives, various functional substances used in separation and analytical methods.
*Illustrative imageSeparating with Ionic Liquids
Ionic liquids, which are salts that are liquid at room temperature, have a dissolving power different from that of ordinary solvents. The lab analyzes how much organic compounds and metal ions can be extracted, and develops new solvent extraction systems that efficiently separate and concentrate rare metals and iodine.
*Illustrative imageHost Molecules That Select Metal Ions
Cyclic metal complexes resembling crown ethers are easy to make through self-assembly reactions and function differently from conventional macrocyclic organic compounds. The lab synthesizes host molecules that recognize lithium ions and other ions well, and works on developing methods to measure metal ions in environmental water and biological samples with high sensitivity.
*Illustrative imageCreating New Functional Substances
Based on what has been learned about the mechanisms of recognition, the lab enhances reaction selectivity and creates new functional substances. It also links these to applications in the separation and analysis of metal ions and other targets.
