ABSTRACT
This study was designed to ascertain the
bio-sorbent potential of plantain peels on some selected inorganic anion
pollutants in brewery effluent. Four different concentrations comprising of O
(untreated), 5, IO and 20 mg/ml of 0, 2, 4 and 8 g of ground plantain peels
dissolved in 400 ml of brewery effluent were prepared. Qualitative and quantitative
determination of chloride ion (Cl), Nitrate ion (NO;), Phosphate ion (PO"
) and Sulphate ion (SO ) on treated and untreated effluents were carried out
after 1 hour. 5 hours, 10 hours, 15 hours and 20 hours using standard
laboratory techniques including spectrophotometric method. Results showed that
decrease in concentration of the selected anions is time and concentration
dependent when both ripe and unripe plantain peels adsorbents were used but it
is more significant in the unripe plantain peels. Therefore, both ripe and
unripe plantain peels could serve as novel bio-sorbents waste water treatment.
Analysis of inorganic anions (CI, NO,y, PO4and SO4) concentrations of untreated
brewery effluent samples were within the range of 5.27mg/l - 529mg/l with nitrate
ion (NO;') recording highest and phosphate ion (PO) having the lowest value.
After treatment, their concentrations decreased within the range of 430.07mg/l
- 3.87mg/l (nitrate - phosphate respectively) for the ripe plantain and 52 l
.40mg/l - 4.36mg/l (nitrate - phosphate respectively) for the unripe plantain.
This is an indication that unripe plantain absorbed more of the inorganic
anions from the water body than the ripe plantain. The Langmuir and Freundlich
adsorption isotherms were used to detennine the suitability of the adsorption
process. The Freundlich isotherm was the most suitable model for this sorption
system and it suggested that the adsorption sites were non-unifonn and
non-specific in nature. The Freundlich isotherms exhibit extremely high R
values indicating, superficially at least, that it produces a considerably
better fit compared to the Langmuir isotherm.
