Variable Effects during Polymerization
S. K. Lunsford
Department of Chemistry, Wright State University, Dayton, OH 45435
Cover
December 2005
Vol. 82 No. 12
p. 1830
Abstract
We developed a lab experiment in which students polymerize 3-methylthiophene onto a polished platinum electrode surface and optimize the conditions (deposition temperature, monomer concentration, deposition time, applied voltage, and electrolyte concentration) for the selective electrode to determine catechol by utilizing cyclic voltammetry. The students learn to use a potentiostat–galvanostat and a cyclic voltammetry instrument while determining the best parameters to detect catechol.
Supplement
Student handout, including the pre- and postlab questions, is available.
