“…While all the prepared bio-adsorbents demonstrated effective removal of Cu, only those prepared from LC adsorbed Fe better. This confirms that locally prepared activated carbon has a strong affinity to removing heavy metals from PW at varying contact times (Popoola et al, 2022). At 6 h, the modified and chemically activated carbons are better adsorbents for Zn, Cu, and Ni when compared with noncarbonized adsorbents prepared from similar materials used in a related study (Udeagbara et al 2021).…”

“…Table 2 shows the adsorption of heavy metals; Zinc (Zn), Nickel (Ni), Iron (Fe), and Copper (Cu) from produced water using the prepared activated carbons. The PW used in this study contained higher concentrations of HMs than reported in recent studies from the Niger Delta area of Nigeria (Udeagbara et al, 2021;Popoola et al, 2022). The results obtained demonstrated the efficiency of the bio-adsorbent in removing heavy metals.…”

“…The Fourier Transform Infrared (FTIR) spectra of the chemically activated carbons, recorded between 4000 and 400 cm -1 are as shown in Figure 3. Varying absorption peaks were displayed on the spectra of the activated carbons, suggesting the presence of active functional groups that will increase the removal of HM from PW (Popoola et al, 2022). In this study, all activated carbons revealed common board peaks from 1628.21 to 1637.94 cm -1 corresponding to the C=O stretch of amine (Ekpete et al, 2017).…”

“…Furthermore, other studies have demonstrated improved removal efficiency of various contaminants in PW using bio-adsorbents processed into activated carbon. Studies investigating possible treatments of PW from Niger Delta oilfields have recently reported improved removal efficiency for crude oil (50 = 74%) (Akinsete and Araoye, 2021) and HM (59 -80%) (Popoola et al, 2022) using activated carbon of bioadsorbents. The removal efficiency of contaminants, especially HM can be further enhanced through the modification of activated carbon using activating agents such as phosphoric acid, nitric acid, hydrochloric acid, zinc chloride, sulphuric acid, potassium hydroxide, and sodium hydroxide (Jankowska et al, 1991;Kumar and Namasivayam, 2009;Reffas et al, 2010;Li et al, 2015;Rahman et al, 2015;Ani et al, 2020;Zięzio et al, 2020).…”

Produced water (PW) during oil and gas production operations contains various hazardous substances including heavy metals (HM) with adverse impact on the environment. Disposal of PW interferes with environmental sustainability, making PW treatment obligatory prior to discharge into the environment. Among previously available treatments of PW, environmentally sustainable methods using low-pore space bio-adsorbents require further development. This study investigated the efficacy of chemicallymodified activated carbon (cMAC) of Luffa cylindrica (LC) and Banana Peel (BP) for the treatment of PW obtained from Niger-Delta oilfield, treated (2, 4, and 6 h) with finely ground (425 μm) carbonized LC and BP impregnated separately with phosphoric-acid and sodium hydroxide. The derived cMAC was characterized by proximate analysis and FTIR spectroscopy. Treated PW was analysed for HM using AAS, Langmuir, and Freundlich isotherms. Obtained values of the surface area for the cMAC from LC were 880 (NaOH), 830 (H 3 PO 4 ) m 2 /g and BP was 810 (NaOH), and 920 (H 3 PO 4 ) m 2 /g. The existence of active functional groups is revealed on the FTIR spectra. Results revealed a substantial drop in HM concentrations (Zn: 30-86%, Cu: 78-88%, Ni: 33-55%, Fe: 17-52%) in PW after treatment with cMAC at varying contact times. All metals (Zn, Cu, Ni) in the treated PW except Fe were below WHO and USEPA guideline limits. Treatment of Niger Delta oilfield PW was effectively improved with acid-modified carbonized L. cylindrica.

“…According to Popoola et al (2022), activated carbon from Citrullus lanatus peel, has proven to be an effective adsorbent in the removal of Pb +2 , Zn +2 , Fe +2 and Cu +2 in water, due to its presence of metal oxides, active functional groups, and large surface area. Alslaibi et al (2014) experimented with adsorption of the heavy metals Fe +2 , Pb +2 y Cu +2 present in wastewater with activated carbon made from olive stone (Olea europaea) with high efficiency (99.32% Fe +2 , 98.83% Pb +2 and 98.55% Cu +2 removal).…”

The problem addressed is the contamination of the Yarinacocha Lagoon water by heavy metals and poor use of agricultural residues. It was manufactured activated carbon from cocoa (Theobroma cacao L.) pod husks and determined its adsorbent effect in removing polluting metals from the waters of the Yarinacocha Lagoon. The response surface methodology was applied with factorial designs 33 and 32, with three replicates to optimize obtaining the adsorbent and measure its effectiveness in metal removal. The modeling of the pyrolysis process resulted in 17.27 g of activated carbon from 295.72 g of dry pod husks, optimal with the following optimal parameters: 150 °C as activation temperature, 450 °C as carbonization temperature, and 2.5 hours as modification time. This resulted in effective removal of pollutant metals (aluminum: 91.43%, copper: 75%, iron: 58.33% and zinc: 58.33%), from waters samples demonstrating that it is possible to manufacture activated carbon from cocoa pod husks, with an adsorbent potential to remove metals from the waters of the Yarinacocha Lagoon.
