Hybridization of the biopolymer with monovalent, divalent, and trivalent metal ions could enhance the flocculating activity. Hybridized biopolymer with divalent metal ion (Ca2+ or Mg2+) obtained the highest flocculating activity compared to that of monovalent (K+) and trivalent (Al3+) metal ions. Biopolymer hybridized with Ca2+ and Mg2+ ions achieved 71.61 and 62.72% flocculation efficiency, respectively, at dosage of 600 mg/L. Electron configuration of the metal ions is the prime factor that affects the formation of bonding between biopolymer and kaolin clay suspension. Under optimum growth condition, B. subtilis was able to produce 4.15 g/L of purified biopolymer with multivalent metal ion hybridization. CHNS/O analyzer has been used to analyze the ratio of C:H:N:S:O elements contained in the biopolymer. Fourier transform infrared spectrum has been used to analyze the functional group of biopolymer and reaction between hybridized biopolymer and kaolin clay suspension. 2016-03-22T03:36:41Z 2016-03-22T03:36:41Z 2015-07-29 Article Desalination and Water Treatment, 2015, pages 1-10 1944-3994 1944-3986 (online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/41180 10.1080/19443994.2015.1074116 en Taylor and Francis Ltd.
