1. Cyclic Voltammetry

이번 실험에서는 전기화학 분석법인 cyclic voltammetry를 통하여 K3Fe(CN)6의 철 이온에 대한 산화, 환원 반응을 진행시키고 전압에 따른 전류의 변화를 관찰하였습니다. scan rate가 증가할 때 peak의 크기를 비교하여 current 역시 비례하여 증가한다는 것을 관찰할 수 있었고 이는 이론과 잘 일치하였습니다. 더불어, E1/2와 Eo 값의 비교하였을 때 두 값이 일치않은 것을 통하여 이번 실험의 반응이 비가역적임을 알 수 있었습니다.
2. Acetaminophen

다음으로, APAP의 pH 의존적인 산화 환원 반응을 진행시키고 전압에 따른 전류의 변호를 관찰하였습니다. 이 반응을 통해 반응 속도의 빠르고, 느림 여부에 따라 scan rate를 적절히 조절해주어야 정상적인 peak를 얻을 수 있음을 알 수 있었습니다.

1. Cyclic Voltammetry

Cyclic voltammetry is a powerful electroanalytical technique that provides valuable information about the redox properties of chemical species. It involves applying a potential waveform to an electrochemical cell and measuring the resulting current. The potential is swept linearly from an initial value to a final value and then reversed, creating a triangular potential waveform. This allows for the study of both oxidation and reduction processes, as well as the determination of kinetic and thermodynamic parameters. The key advantages of cyclic voltammetry include its ability to provide information about the reversibility of a redox reaction, the number of electrons involved, and the presence of intermediate species. It can also be used to investigate the kinetics of electron transfer reactions and the adsorption behavior of species on electrode surfaces. Additionally, cyclic voltammetry is widely used in the characterization of electroactive materials, such as those used in energy storage devices, sensors, and catalysts. Overall, cyclic voltammetry is an essential tool in the field of electrochemistry, enabling researchers to gain a deeper understanding of the fundamental electrochemical processes occurring in a wide range of applications. Its versatility and ease of use make it a valuable technique for both academic and industrial research.
2. Acetaminophen

Acetaminophen, also known as paracetamol, is a widely used over-the-counter medication that is effective in relieving pain and reducing fever. It is one of the most commonly used drugs in the world, with a long history of safe and effective use when taken as directed. One of the key advantages of acetaminophen is its relatively low risk of side effects when used at recommended doses. Unlike non-steroidal anti-inflammatory drugs (NSAIDs), acetaminophen does not have the same risk of gastrointestinal side effects, such as stomach ulcers or bleeding. This makes it a particularly useful option for individuals who may be more susceptible to these types of side effects, such as the elderly or those with certain medical conditions. However, it is important to note that acetaminophen can be potentially harmful if taken in excessive amounts or in combination with other medications that also contain acetaminophen. Overdose of acetaminophen can lead to serious liver damage, and it is crucial for individuals to follow the recommended dosage guidelines and to be aware of the potential for interactions with other medications. Overall, acetaminophen is a safe and effective medication when used as directed, and it continues to play an important role in the management of pain and fever in a wide range of clinical settings. As with any medication, it is important for individuals to consult with their healthcare providers to ensure the appropriate use and to be aware of any potential risks or contraindications.
