WebJul 3, 2008 · Pure H 2 S gas (99.9%) was sparged in the absorber unit for about 35–45 min. In the absorber unit, Fe 3+ –malic acid chelate solution oxidized H 2 S gas to elemental sulfur and simultaneously active ferric chelate was reduced to inactive ferrous chelate (reaction 2). After complete reduction of ferric chelate, H 2 S conversion to elemental ... A H-bridge is an electronic circuit that switches the polarity of a voltage applied to a load. These circuits are often used in robotics and other applications to allow DC motors to run forwards or backwards. The name is derived from its common schematic diagram representation, with four switching elements configured as the branches of a letter "H" and the load connected as the cross-bar. pilot pen sweepstakes
