Abstract
Industries commonly produced a large scale of wastewater that consisted of hazardous materials such heavy metals. Recently, one of popular methods for wastewater treatment was adsorption system using biosorbent. Sago bark (Metroxylon sagu) was a solid waste remained from sago starch industry. It contained various functional group such as carbonyl and hydroxyl groups that could be utilized to resolve wastewater containing metal ions. Removal of Cr(VI) and Pb(II) using sago bark (Metroxylon sagu) have been investigated by a fixed bed column reactor. The effect of flow rate (2, 4, 6 mL/min) and bed depth (3, 6, 9 cm) was examined in order to observe column performance (15x1 cm id). The result revealed that the lower flow rate and the higher bed depth delayed the breakthrough time and exhaustion time. Thus, the optimum conditions were achieved at 2 mL/min of flow rate and 9 cm of bed depth for both metal ions. The equation of Thomas, BDST and Yoon-Nelson models was carried out to evaluate the breakthrough curve. The repeatability and regeneration of sago bark were analyzed by HNO3 0.01 M within 3 cycles. It means that sago bark has a promising ability to remove Cr(VI) and Pb(II) ions in solution.
