Abstract
Spectrophotometric determination of the chelating behavior of metal ions and EDTA encapsulated in sol-gel matrix Carter Barnes and Catrena H. Lisse, Ph.D. Department of Chemistry, Physics and Astronomy Georgia College and State University Ethylenediaminetetraacetic acid (EDTA) has numerous medicinal applications across a wide variety of fields, including veterinary medicine. Magnesium and calcium ions, in excess, can negatively affect the quality of life for many animals and can be destructive to certain medical devices due to mineralization. Using the chelating ability of EDTA, the complexation of metal cations with EDTA can result in decreased amounts of metals in the system. This project investigated EDTA encapsulated within a silica sol-gel matrix with a metal cation sensitive dye, pontachrome violet SW. When placed in a cation rich environment, ultraviolet/visible (UV/Vis) spectroscopy was used at 575 nm to determine the concentration levels of the target ions isolated by the EDTA sol-gel matrix. This presentation will highlight the experimental methodology and preliminary results of the study.
