Sol-Gel Technology In Enhancing The Filtration Of Semi-Volatile Organic Compounds, David T. Nguyen, Jennie Ash, Chastity Ellison Jan 2007

Sol-Gel Technology In Enhancing The Filtration Of Semi-Volatile Organic Compounds, David T. Nguyen, Jennie Ash, Chastity Ellison

The Corinthian

For the past several years, the field of sol-gel technology has undergone remarkable growth in areas ranging from micro-fibers to chemical sensors. Incorporating an organic phase into the colloidal mixture via pre- or post-doping can modify sol-gels, and manipulation of the size of the pores can be used in developing 'eco-friendly' water filters, particularly for filtering semi-volatile organic compounds in water. In this research project, various forms of sol-gels were made to see which is more efficient for certain semi-volatile chemicals that can be found in diverse sources of water. Organically modified silicates and different structurally sound sol-gels were made …

The Corinthian

A simple apparatus was constructed for an undergraduate physical chemistry laboratory to determine a mathematical model of wavelike motion. The apparatus was assembled by attaching an airflow valve connected to a tank of argon gas to a GC column, thus creating regulated airflow. The air was manipulated to gently flow over a small sensitive microphone that was attached to an inexpensive resonator. A model will be developed to measure the speed of sound that will lead to the measurement of the molar mass.
