“…Daouda et al [41] successfully synthesized and optimized an agricultural waste adsorbent made from coconut shell for AMX removal by using the response surface methodology (RSM) with two considerations: the impregnation ratio (IR) and the activation temperature. The AC made from coconut shells showed its best qualities with a significant microporous specific surface (S BET = 437 m 2 /g and V micro = 0.21 cm 3 /g), optimum iodine adsorption (930.28 mg/g), amorphousness, and a low heterogeneous composition.…”

Antibiotics and non-steroidal anti-inflammatory drugs (NSAIDs) are among the top pharmaceutical contaminants that have been often found in the aquatic environment. The presence of these contaminants in the aquatic environment is of great concern since it has a negative impact on both ecology and human health. In contrast to other tertiary treatments, adsorption stands out as a viable treatment approach since it provides benefits such as easier operating conditions with no byproduct formation. Commercial activated carbon is widely researched as a pharmaceutical adsorbent, but its large-scale applicability is constrained by its high cost. Agricultural waste also contains a large amount of various functional groups, which may be adapted to surface modification to increase its adsorption ability. In this regard, this study is designed to review the recent progress of efficient adsorbents derived from various agricultural wastes for the removal of antibiotics and NSAIDs contaminants from water bodies. Adsorbents made from agricultural waste have important benefits over commercial activated carbon for the reduction in waste while controlling water pollution.

The presence of pharmaceuticals in natural waters has been the subject of numerous studies in the last decade due to their potential negative effects on human health and the environment. Indeed, the intensive use of pharmaceuticals leads to their presence in municipal wastewater. Unfortunately, international and national regulations still do not require continuous monitoring of the presence of pharmaceuticals in natural waters and drinking water, so wastewater treatment plants do not focus on removing them from wastewater. Diclofenac, 2-[2-(2,6-dichloroanilino)phenyl]acetic acid (DCF), is a nonsteroidal compound used as an analgesic, anti-inflammatory, and antipyretic drug and is therefore commonly found in wastewater. Due to its properties, DCF remains biologically active in the aquatic environment and easily enters the food chain. Therefore, DCF should be removed from wastewater before it is discharged into water bodies. Adsorption is an efficient and simple method that can be used to remove DCF from water. In this study, the possibility of removing DCF by adsorption on activated carbon is investigated. Modified hazelnut shell (MHS), modified commercial activated carbon Cullar (MC) and unmodified commercial activated carbon Cullar (C) were batch tested as adsorbents. The tested adsorbents were characterised by FTIR, zeta potential and pH pzc , while the adsorbent efficiency was tested in the pH range from 2 to 10 and described by isothermal studies. Among the tested adsorbents, the maximum uptake of 48.7 mg g −1 was found when modified activated carbon Cullar was used, while both Freundlich and Langmuir isotherm models fitted well to the data. Modified activated carbon from hazelnut shells showed effective removal of DCF.

“…These metals accumulate in both the food chain and the human body, resulting in various health effects and potential fatality [5] [6]. While heavy metals in drinking water can originate from natural geological sources or industrial activities [5], several standard methods, including chemical precipitation, evaporation, ion exchange, electrolysis, and reverse osmosis, have been explored to eliminate heavy metals from drinking water [8] [9].…”

A large portion of the water environment is being contaminated and destroyed due to the direct liberation of industrial effluents, agricultural and municipal activities that are toxic to humans, animals, and plants. Among the several pollutants, heavy metals are considered to be a serious hazard and the presence arsenic in water will cause carcinogenic to humans. In this study, for sustainability easily available eco-friendly materials were used for the adsorption of heavy metal. An aqueous solution of zinc and arsenic metal was prepared and adsorption of heavy metal was performed by varying pH, initial concentration, time, and dosage. The metal productivity was optimized using Response Surface Methodology (RSM) with central composite design (CCD) by varying the obtained data. The model prediction result is in agreement with experimented result (R2=0.9706, 0.9799 adj R2=0.9432,0.9572 for and coconut shell carbon). ANOVA table shows that the adsorption of arsenic and zinc metal to carbon made from coconut shell. The optimization of carbon made from coconut shell pH, initial concentration, time, and dosage found to be the maximum adsorption capacity of both adsorbent pH (7,7), initial concentration (40,30), contact time (60,90), adsorbent dosage (0.3,0.3) was obtained. Characterization of activated coconut shell carbon was carried out by SEM.
