“…Naboulsi et al [94] generated activated carbon from Ritama-Monosperma (L.) Boiss powder through carbonization at 500 • C and activation with H 3 PO 4 . The influence of various experimental parameters (pH, temperature, adsorbate dose) on the equilibrium, kinetics, and thermodynamics of 2,4-D and 2,4,5-T adsorption from a bicomponent solution was evaluated.…”

An overview of different adsorbents, based on agricultural and household waste, for chlorophenoxy herbicides removal from water is presented. Several groups of adsorbents are discussed, taking into account the modification method used on the initial material and the type of final product obtained. The adsorbent characteristics and the conditions of the adsorption measurements are given, and a discussion on the obtained results is presented, along with a theoretical description, following the application of various equations and models. A group of the most effective adsorbents is indicated, based on the analysis of the adsorption capacity, towards 2,4-D and/or MCPA, and the adsorption rate. Some important problems connected with adsorbent utility are discussed, taking into account economic and ecological aspects. Moreover, the effectiveness of the analyzed materials is observed through the analysis of its interactions with other components present in real systems.

“…Importantly, this work is novel in its use of a modern scientific tool to establish the theoretical retention mechanism between the pesticide and activated carbon from PPS. This tool is known as the density functional theory (DFT), which is increasingly used in predicting reaction mechanisms between various systems consisting of adsorbent and adsorbate [46][47][48][49][50][51].…”

This study proposes an innovative approach based on the concept of the circular economy. It involves treating deltamethrin-contaminated water using an activated carbon (AC) adsorption technique based on a highly adsorbent plant waste derived from prickly pear seeds (PPSs). Activated carbon was prepared from PPS via a simple pyrolysis process preceded by chemical impregnation with phosphoric acid. Thus, a whole range of physicochemical tests were carried out, including iodine number (QI2), methylene blue number (QMB), Bohem dosage, pHZC, Brunauer–Emmett–Teller analysis (BET), and scanning electron microscopy (SEM). The QI2 and QMB were, respectively, 963.5 (mg g−1) and 8.3 (mg g−1). The pHzc of activated carbon was 2.5, and the surface area BET was 1161.3 m2 g−1. Adsorption kinetics, isotherms, and thermodynamic studies of pesticides using activated carbon were established. The obtained results revealed that the adsorption of the pesticide by the activated carbon appeared to be chemisorption with an adsorption capacity of 1.13 mg g−1. The adsorption capacity increased with increasing temperature, which explains an endothermic adsorption interaction. These results are in agreement with the results found using the density functional theory (DFT) and showed that activated carbon has an interesting adsorption power, which makes it as efficient as commercial activated carbon and predisposes it to the depollution of aqueous solutions contaminated with pesticides.
