Chemistry 355 Term Paper

Students are required to identify a manuscript from the scientific literature that utilizes one of the analytical methods discussed or related to one of the methods discussed in class and write a short term paper discussing the method. For example, the manuscript can be related to the quantitative analysis of a specific analytical target species such as an anion (sulfate, nitrate, phosphate, chloride), a (trace) metal, a reducing agent (vitamin C) or an oxidizing agent (hydrogen peroxide). Alternatively, the selected paper may be related to the characterization of some material such as a polymer (acid base properties or metal binding capabilities), a protein, or to the characterization of some environmental issue. The paper must be from a chemistry journal (or allied science). The student will discuss the nature of the analytical problem and how the method is utilized in the paper to “solve” the problem and alternative approaches. You should select a topic/manuscript presented it to me for approval. The selected manuscript (method) does not have to be related to a complex or complicated problem (keep it simple).

METHODS: You should aim to select a topic from one of the following four areas. a. Precipitation (i.e., gravimetric analysis, chemical deposition, electrochemistry) b. Complexometric titration c. Acid/Base (i.e., potentiometric titration) d. Oxidation/Reduction (i.e., electrochemistry/ potentiometry, titration) e. Ion specific electrodes (titration, speciation) f. Chemical speciation (i.e. metals, material surface protonation).

The term paper will be broken down into the following categories. Cover page

The cover page will include your name, the topic assigned, and the citation for the paper identified by the student that will be used for this term paper. The cover page will be attached to the term paper.

1. Abstract (~ 1/4 page single spaced): The abstract should provide the reader with a brief overview of the work. It should answer the questions what is being measured or characterized and what method is being utilized.

2. Introduction (1/2 -1 page double space): The introduction should provide the reader with an introduction to problem being addressed, the types of samples examined, and the method being utilize to quantify the specific analyte or to characterize he material you have selected.

3. Experimental (~1 page double space): Provide a brief description of the experimental method and how it is applied in the paper.

4. Discussion (~2 page double space): Discuss the success and limitations of the method that is utilized in the selected manuscript. In addition, alternative analytical approaches should be briefly described in this section. References should be provided for alternative methods. Methods can be compared in terms of ease of implementation, analytical sensitivity (detection limit) and precision.

5.Conclusion (~ 1⁄2-1 page double spaced): Overall assessment of reviewed paper and a discussion of the success and limitations of the method in solving the stated problem. For example what are the concentration limitations and what sort of sample matrices are conducive to utilizing this approach.

6. Citations: Literature citations: You are expected to identify supporting literature relevant to the paper you use in your term paper. Web citations are generally not adequate. The supporting literature must be from reputable, peer reviewed, journals. It should be in the following format on a single page attached at the end of the term paper: Authors, Title, Journal, Year, Volume, Pages. This page is in addition to the 3-5 pages of text associated with the term paper.
