Quaternized rice husk as sorbent for reactive dyes


Low, Kun She and Lee, Chnoong Kheng (1997) Quaternized rice husk as sorbent for reactive dyes. Bioresource Technology, 61 (2). pp. 121-125. ISSN 0960-8524; ESSN: 1873-2976


A study on the sorption of hydrolyzed Reactive Blue 2 by quaternized rice husk showed that the binding capacity of the sorbent was not suppressed by dyebath conditions of high concentration of electrolytes. Its sorption capacity decreased with increasing concentration of NaOH. Complete regeneration of dye-coated quaternized rice husk was not possible under base treatment, suggesting chemisorption of dye molecules on the sorbent material. The physical stability of the quaternized rice husk was examined by treating it with various concentrations of NaOH solution. Results showed that no dissolution of sorbent occurred, even in 1 M NaOH solution.
