The performance of starch in removing these heavy metals was compared with that of polyethylene glycol (PEG) a commonly used polymer in PEUF processes. Rejection coefficients and flux were studied under different values of pH solution and metal ion concentrations maintaining the transmembrane pressure constant at 1.5 bar. At pH 7, and starch concentration of 0.05%, the rejection was the highest at around 90%. As metal ion concentration increased from 10 to 50 mg/L, the rejection of metal ions decreased. It was found that starch gave higher rejection for Zn (II) and Cr (III) at 0.05 g/L of polymer concentration, whereas 1 g/L of PEG concentration gave higher rejection for Cr (VI) at 10 mg/L. The influence of metal ion concentration on Pb (II) rejection is not significant for the two selected polymers. The rejection of these metal ions by starch in this study is found to be influenced by granule structure that generally behaved in a non-ionic manner. 2016-04-01T01:38:09Z 2016-04-01T01:38:09Z 2015 Article Environmental Progress & Sustainable Energy, vol. 34 (2), 2015, pages 359–367 1944-7450 (Online) 1944-7442 (Print) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/41241 10.1002/ep.11995 en John Wiley and Sons Inc.
