A B S T R A C TThe use of alternative materials for environmental decontamination has been intensively studied. In this study, the capacity of banana peels treated with sodium hydroxide (NaOH), hydrochloric acid (HCl), and phosphoric acid (H 3 PO 4 ) to adsorb Pb (II) was evaluated. The physical and chemical changes on the banana peels after chemical treatment were evaluated by infrared spectroscopy and scanning electron microscopy. Batch adsorption experiments were carried out as a function of pH, time, metal concentration, and temperature; desorption tests were also performed. Pb (II) concentrations were determined by flame atomic absorption spectrometry. An increase in the adsorption capacity of the modified and natural peels was observed in the pH range of 3-5, and pH 5 was adopted for further experiments. The adsorption system reached equilibrium in 300 min, and its kinetics followed the pseudo-second-order equation. From adsorption isotherms, it was observed considerable enhance on adsorption capacity of banana peels, especially with treated with NaOH. Besides, the negative Gibbs free energy variation values showed that the Pb (II) adsorption was spontaneous. Moreover, the improvement in the Pb (II) desorption for the modified peels was observed, indicating that the proposed material can be reutilized.

“…Although the sorbent we used is a raw material (not modified) that shows good OSC. DPF having good sorption capacity due to the present of large lumens as well as the oleophilic lignin layer which contributed to enhance the oil sorption of DPF, comparing with others sorbents which have lower sorption capacities [22,[31][32]. Recycled wool-toasted nonwoven material having higher oil sorption capacity than this research work may be due to higher surface area which increase the oil adsorbed onto the material as will as higher contact time.e.g.10 min.…”

Crude oil spill are a global concern due to the environmental and economic impact as well as harm the beauty of the polluted sites. Date Palm leaves fiber (DPLF) as a natural agricultural fiber, which is environmentally materials, biodegradable, renewable, abundant, and cheap. A hollow cellulosic material like DPLF is a potential sorbent to counter the oil spill pollution. The oil sorption capacity (OSC) of fresh and weathered oils into DPLF as a sorbent was studied. The effects of contact time and temperature on sorption were studied in simulated tap water as well as salty water. The OSC increases with increasing the contact time. The DPLF has given oil sorption capacity of 4.534-7.985 g oil/g sorbent for a contact time of 5-90 min for fresh oil (tap water, at room temperature). This OSC are considered to be good for a sorbent considering it is locally available and not expensive. Fresh oil is having higher OSC at room temperature at all the experimental times (5-120 min). At lower temperature, e.g. 15 °C the adsorption of oil having greater role in increasing OSC, since at low temperature the oil having high viscosity and that will increase the adherence of oil onto the surface of the fibers and within the capillary during drainage. At room temperature and little higher e.g. 25 & 30 °C , the oil will have less viscosity and more diffusion and that will increase the absorption within the internal capillary and lumens of the fibers and that increase the OSC. There is decrease in viscosity at higher temperature e.g. 45 & 60 °C that will increase the diffusion in the oil and increase the segmental mobility of the fibers as well as increasing the penetration of oil into the pores and lumens of the fibers. That will increase the OSC, but much oil will come out during the drainage time (5 min).
