Applicability of ferric(III) hydroxide as a phosphate-selective adsorbent for sewage treatment

This research was undertaken to evaluate the usability of ferric(III) hydroxide for phosphate removal from sewage. Batch adsorption experiments, partly fixed bed column experiments, were conducted to study the influence of various factors, competing anions and contact time on the adsorption of phosp...
