Removal of PAH Anthracene from Aqueous Media using Banana Peel Activated Carbon

Abstract

Abstract. Anthracene, a three ringed polycyclic aromatic hydrocarbon is a widely known hazardous ubiquitous environmental pollutant. The present study investigates the efficiency of activated carbon developed using banana peel as a precursor material. The influence of variation of shaking time, adsorbent dose, initial concentration, temperature and pH has been studied under a set of diverse conditions. The amount of anthracene in aqueous medium continuously decreases with the shaking time and acquire a constant value after 70 min. The adsorbent dose of 8 mg was found to be sufficient for the adsorption of anthracene in the present study. The maximum adsorption of anthracene was at pH 2 and it was reduced with the increase in solution pH. Among the studied temperature range, the removal of anthracene was higher at 50 °C, indicating endothermic nature of the adsorption. The data obtained were analysed with Langmuir and Freundlich adsorption isotherms and parameters corresponding to both isotherms were evaluated. The work provides an efficient method for the removal of priority pollutant anthracene from aqueous media.

Waste newspaper driven activated carbon to remove polycyclic aromatic hydrocarbon from wastewater

“…The availability of active sites for the adsorption of pollutants might be the possible reason for this sharp increase [ 39 ]. Although a gradual increase in removal efficiency to 94.958% is observed with a further rise of dosages from 0.06 to 0.10 g. Overcrowding of adsorbate molecules results from overlapping of adsorbent sites at high adsorbent dose which causes unsaturation in the increased active sites and facilities gradual rise despite faster at high adsorbent dosage [ 40 , 41 ]. Similarly, for IP, a significant Re is observed for dosage from 0.02 to 0.06 g with a value between 57.644% and 92.374% ( Fig.…”

“…4 a). However, a slight decline in removal efficiency is observed to 0.1 g. Unsaturation of adsorbent sites due to overcrowding of adsorbate molecules might be the probable reason for this decline [ 40 , 41 ]. Li et al [ 22 ] reported that the removal efficiency of p -nitrophenol through activated carbon aerogels (ACA) was increased quickly to 96.2% up to dosage 0.4 g L −1 , and then the increase of rate gradually slows down at higher dosage.…”

Decontamination of cationic dye brilliant green from the aqueous media

“…The adsorption rate was found to decrease with increase in pH. The adsorbent BPAC also showed maximum adsorption at pH 2.0 for anthracene removal from aqueous medium (Gupta and Kumar, 2016). Rehman et al (2011) also reported the maximum adsorption of brilliant green dye in acidic medium on radish peels as well as on coal.…”

Application of Activated Carbon Banana Peel Coated with Al2O3-Chitosan for the Adsorptive Removal of Lead and Cadmium from Wastewater

“…The synthesis of activated waste banana peels was adopted from the literature with some modifications [35]. Waste banana peels were collected, washed, and dried in the oven at 100 • C. Dried peels were then crushed into a fine powder using a pestle and motor.…”
