Abstract

Indoor pollution has been studied broadly in recent years due to the issue it represents in public health. This work presents the development of different modified electrodes having opal-like and inverse opal-like structures, to be used as collector plates in an electrostatic precipitator for the deposit of particles suspended in air. Some aspects of the modification of the electrodes in electrostatic precipitators have been analyzed in order to increase the efficiency and capacity for capturing these suspended particles, exchanging the flat plates currently used as collectors for opal-like and inverse opal-like structures. To accomplish this, we studied alternative routes of obtaining these structures. In their preparation, electroless and electrolytic metal deposits were carried onto glass spheres of different sizes, as well as using tin melting for obtaining inverse opals. The best route for preparing opal-like structures of desired sizes was plating of glass beads of 4mm in diameter, while for inverse opals, the most viable way was with tin melting. Also, tests were conducted on electrostatic precipitators with plates of opal-like and inverse opal-like structures, metallic foams and plates. The inverse opal-like structure shows advantages and disadvantages as an electrode for electrostatic precipitators.
