Adsorptive Removal of Synthetic Organic Compounds in Aqueous Solutions by Fresh Nipa Palm Fronds

Adsorptive removal of contaminants in wastewater is distinctive because the technique is simple, effective and with low cost, however, the flexibility of the adsorption process is actually contingent on the sorption abilities of the adsorbent. Nipa palm has been tested in several studies to be effective due to its porous structure and surface properties. Hence, the objective of this paper was to evaluate the adsorptive removal of synthetic organic compounds (SOCs) in aqueous solutions using carbonized and surface-modified carbons produced from Nipa Palm (Nypa Fruticans Wurmb) fronds using chemical oxygen demand (COD) as the index of measurement. Data obtained for the present investigation revealed that percent COD reduction of SOCs by the carbons ranged between 93.81 – 96.67%, while COD reduction capacity estimated by Langmuir-type model was between 1.77 - 11.83 mg/g at ambient temperature and at an optimum pH of 8.5. Thermodynamic assessment by Gibbs free energy (∆Go, KJ/mol) revealed that ∆Go values were negative (from - 1.45 KJ/mol to - 5.89 KJ/mol). The results obtained show that Nipa palm could be a beneficial source for the development of an eco-friendly and locally available activated carbon for removal of organic contaminants from domestic and industrial wastewaters.
