Removal of phosphate from electrocoagulation post-treatment phosphate reduction using Octolig®
1a Institute for Environmental Studies, Department of Chemistry , University of South Florida , Tampa , Florida , USA.
Abstract:
The present study examined the removal of phosphorus following electrocoagulation post-treatment using a sample from a commercial firm. Samples were subjected to column chromatography using Octolig® a polyethylenediimine covalently attached to high-surface-area silica. Two commercial samples with significantly different phosphorus concentrations were evaluated: 10.2 ppm from polyphosphates and raw sample of 983 ppm P. After passing over Octolig®, the sample phosphate concentration was reduced to values of <0.05 ppm P.
