An Environmental Engineering Scientist
His Contributions to Water
Chemistry


Chemistry of Organic Matter
Dr. Black incorporated electrophoresis technology into
extensive research involving waters containing organic matter.
His 47 years at the University of Florida provided him with
access to natural waters high in organic matter in close
proximity to his laboratory in Gainesville.
His work with fulvic acids increased understanding of their
complexities, through solubility relationships, chemical spot
tests, and infrared absorption spectra, and he reported that
ozone was more effective than chlorine or chlorine dioxide in
removing fulvic acids from water.
He studied the removal of organics from waters using ferric
sulfate, and reported a method for optimal conditions for
removing organic color from relatively soft, colored waters.
Ferric sulfate proved to be a very effective coagulant when
compared to alum, over a broad range of pH levels.
