About this document
Chromium Uptake by Alginate Beads by Sebastian Andres Zapata Ahumada is a document available to read on EtoBox.
This document summarizes research on using protonated dry alginate beads (PDAB) to uptake trivalent chromium from aqueous solutions. Key findings include: 1) Uptake of chromium by PDAB was strongly dependent on solution pH up to around pH 4.5, with a maximum uptake of 112 mg chromium per g of alginate beads observed at pH 4.5. 2) Uptake involved an ion exchange mechanism where protons were released from the PDAB in exchange for chromium ions. 3) Scanning electron microscopy and electron probe microanal
