Proposed Research Project

Determination of Acetaminophen in a Children's Pain Relief Elixir

Compact Voltammetry Cell

General Information

Advisor: Professor Brad Sturgeon

Proposal

Acetaminophen is used as a pain reliever and fever reducer. It is the active ingredient in children’s Tylenol which is formulated as a viscous liquid elixir. This research determines the acetaminophen concentration in a sample of elixir using a compact voltammetry cell and applying the cyclic voltammetry which is an electrochemical method.

Instruments to be used

WaveNow ™ USB potentiostat with AfterMath ™ software.

Research pledge

I, Mirna Alhanash, have read the Chem/Bioc 430 course syllabus and understand the general structure and expectations of the research program. The above material was prepared after consultation, and in conjunction with my research advisor.

ACS Guide to Research Reports

Research students are expected to write a report and submit it to the research coordinator by the last day of regular semester classes. These reports are intended to summarize the data collected over the course of the semester. Since this research course requires you to enroll in at least two semesters of research, two reports will be generated. The first semester report should be considered a work in progress, where as the final report should be a more comprehensive summary of your research project. These reports are necessary since several researchers may work on each project. The report will be organized so that it is clear what material is new and what material is review. When available, research students will be provided with an electronic copy of the latest report on their project. The research student is expected to update and improve the introduction, background, and literature sections with each report. Results that challenge earlier conclusions will be justified in a discussion section. Reports will be submitted in both electronic and hard copy to the Faculty Research Advisor AND Research Coordinator.

2. Introduction

State of the motivation for the project of interest in terms of current literature. When we make reference to current literature, this is where you provide specific reference(s) to this work. This section can be largely copied from an earlier report(s), if they exist, but it is expected that this section is edited to include newly found background information. Note: if the author of previous report(s) is included as a contributor to the project, you may cut and paste text; this is not plagiarism, it is collaboration.

3. Background from earlier reports

This section will summarize the work reported in earlier reports. If significant results were presented in the most recent report, these results will be summarized and in most cases can be added to that reports background section. This section is included mainly to confirm the current students overall understanding of the project.

4. Experimental

This section describes experiments done during the period covered by the report. Usually, this work will be similar or identical to that described in the prior report, if they exists. Any new experiments will be written up and added to the experimental section. Any experiments preformed under identical conditions need only reference previous reports.

Example:

Reagents: List reagents used by product number and the source.

Enzyme Reactions: All enzyme reactions were done using a totlal volume of 5.0 mL. Substrate concentration ranged between 1-12 mM. Reactions were initiated be the addition of enzyme.

HPLC: HPLC data was collected using the Waters Breeze HPLC with a C18 column (insert specs here). Specific HPLC conditions are given in the figure captions.

UV-Vis: UV-Vis data was collected using the HP 5832 UV-Vis spectrometer using a quartz cuvette. Sample concentrations were adjusted so as to not exceed 1.0 absorbance unit. Significant data was exported in the ".CSV" format and then worked up in Igor.

5. Results

This section documents the results of the experiments done during the period covered by the report. Tabulation of data is encouraged; representative spectra presented.

Peak vs Concentration Acetaminophen

The concentration of Acetaminophen in Elixir was determined to be around 140 mg for every 5 ml.

6. Discussion

In this section, the student will discuss the results of their work in context of the literature and the results of earlier reports. Questions that have been raised in earlier reports may be addressed here.

Percentage of experimental to labeled concentration was 90%(±2%)

7. Conclusions

Restate the findings of this period of research. The statement “No conclusions have been reached,” is an acceptable statement.

8. Future Directions

In this section, the student will discuss possible experiments intended to address unanswered questions or technical problems on the project.
