Abstract

Nipa palm fruit fibre was carbonized at 400oC in a muffle furnace and used to remove kerosene in contaminated water in a batch experimental process with chemical oxygen demand (COD) reduction as the measurement parameter. The elimination of kerosene in the contaminated water was studied by applying the effect of carbon dosage and initial contaminant concentration. The results obtained showed that, the best process conditions for removing kerosene in the contaminated water samples were 8.0 mg carbon dosage at low concentration of 20 mg/L of kerosene contamination. The adsorption isotherm of the elimination process was evaluated by Langmuir and Freundlich isotherm models and the data fitted better to Freundlich isotherm (R2 = 0.84) when compared to Langmuir isotherm (R2 = 0.88). The maximum monolayer surface coverage as computed from the Langmuir equilibrium adsorption data was 1.43 mg/g. The overall outcome indicates that the carbonized carbon produced from Nipa palm fruit fibre has low ability in reducing kerosene from contaminated water.

Highlights

By-products are the most commonly encountered water contaminants in the Niger Delta region of Nigeria due to incessant artisanal and small-scale refining of crude oil in the region (Horsfall and Abia 2003)
Delta region of Nigeria (Adowei et al, 2014; Isiuku et al, 2013) where drinking-water sources rely heavy on Removal of Low Concentration of Kerosene from Water Using Nipa Palm (Nypa Fruiticans Wurmb) Fruit Fibre borehole sources
In this paper we report the removal of kerosene in water contaminated with minute amount of kerosene using carbonized carbon made from Nipa Palm (Nypa Fruiticans Wurmb) Fruit Fibre in a batch adsorption process using chemical oxygen demand (COD) as the index of measurement

Summary

Introduction

By-products are the most commonly encountered water contaminants in the Niger Delta region of Nigeria due to incessant artisanal and small-scale refining of crude oil in the region (Horsfall and Abia 2003). These contaminants may be present in solution in emulsified form, dissolved, or floating films and they are capable of representing a substantial threat to almost all organisms living in the region of the polluted water bodies or areas. Clear liquid obtained from fractional distillation of petroleum between 150 deg C and 275 deg C, with typical density between 0.78 and 0.81 g/cu cm. Very stringent standards are required for the regulation of oily contaminants in drinking water and water meant for disposal
