Aim:2 Expanding the Application of Conductive Polymer for Solid Phase Extraction
2.1 (New Direction) Application of Polypyrrole based Conductive Polymer Coating Material for Extraction, Determination and Quantification of Active Ingredient in Personal Care Products
2.1.1 Introduction
Triclosan is commonly used in personal care and household products such as shampoo, toothpaste, soaps, detergents, skin care creams and lotions because of its antimicrobial properties. As per US food and drug agency (USFDA) the typical concentration of triclosan should not exceed 0.3% (w/w) of product weight42. The reports suggest that triclosan is transported to municipal wastewater treatment plants through domestic sewage and finally discharged in aquatic environment from wastewater effluent43. The …show more content…

Triclosan has been found in river water, lake water, fish and human milk44. Apart from these effects of triclosan, these compounds are also known to have endocrine disrupting effect particularly regarding thyroid hormones homeostasis45. Thus, it is very important to develop methods that can selectively determine and extract triclosan from environmental waters.
Several analytical techniques have been used for determination of triclosan such as gas chromatography-mass spectrometry (GC-MS)46, liquid chromatography-mass spectrometry (LC-MS)47, high performance liquid chromatography-UV(HPLC-UV)48, and capillary electrophoresis-UV (CE-UV)49. Various analyte pre-concentration techniques such as liquid-liquid extraction(LLE)50, solid phase extraction

    Traveling from the U.S. mint into the hands, pockets, and wallets of citizens, ultimately, pennies will develop a dirty look due to daily interactions with their surroundings. In recent years, many have discovered possible solutions to restore the original shine of copper pennies. In order to determine what solution most effectively sterilizes our common pocket money, it is crucial to understand what makes pennies dull in the first place and what can counter this reaction. Over time, pennies receive a dark coating, creating a dull appearance.

    In this lab, three unknown compounds were separated from a mixture and identified by melting point. Unknown mixture #124 has components of acid, base and neutral compound. The compounds were identified by melting point and matched up with the known melting points from a given list. In order to identify the compound it was important to separate by dissolving the mixture in an organic solvent which was not soluble in water, and then extracting the solution first with HCl, and then dilute sodium hydroxide solution. From the separation mixture, the aqueous layer were obtained and labeled as TT-1 (base), TT-2(acid) and TT-3 (neutral) in three different test tubes for later recovery.

    The purpose of this experiment was to isolate the three components of Excedrin using column chromatography. Thin layer chromatography (TLC) was used to determine when each of the components had been fully eluted from the column. If there was an overlap in fractions between two components, liquid- liquid extraction was done to separate them. The compounds were characterized via NMR instrumentation and the percent recovery for each compound was calculated to determine whether the isolation was

    Advancement in chemical research has given companies the ability to make increasingly more effective products. These companies are allowed to manufacture goods with newly discovered synthetic compounds, often without much rigorous testing to determine if they are safe. An apparent correlation between the recent use of industrial chemicals and occurrences of disease in the population has been found, suggesting that they may be harmful to people’s health. Studies have shown that many commonly used ingredients can interfere with hormones, causing reproductive and developmental harm and even cancer. With the wide range of negative effects possibly caused by these substances, attention needs to be brought to regulation of chemical use in order to protect the health of the public.

    In the first chapter of “Living Downstream” by Sandra Steingraber discussed about personal experiences living in Illinois and discovering how much the landscape has changed over the years. In addition to the changing landscape, cancer, especially breast cancer, has increased in the prairies of Illinois and pesticides usage may cause. Much of the discussion first begin with the change of landscape as the prairies of Illinois has become a place for farming and pesticides. As farming became an important aspect of Illinois, pesticides were created to remove any bugs or insects from the product that is being farmed. A few pesticides formulas that came to be are atrazine, dichloro diphenyl trichloroethane (DDT), and polychlorinated biphenyls (PCBs).

    TLC was used to identify the actual unknown product as well as other products/reactants present in the filtered solution. The procedure was conducted by placing a TLC plate in a developing chamber that is filled with a small amount of solvent. The solvent cannot be too polar because it will cause spotted compounds on the TLC plate to rise up too fast, while a very non-polar solvent will not allow the spots to move. The polarity of the spots also determines how far it moves on the plate; non-polar spots are higher than polar ones. After spots on the TLC form, the Rf values are calculated and used to analyze the similarity of the compounds.
