“…Comparing the obtained R 2 values of the applied models, the Langmuir and Freundlich equations describe the experimental data the best. This indicates that during the adsorption of 2,4-D, both chemical and physical interaction processes occur between the adsorbate and the adsorbent [35]. It is clear that the Langmuir isotherm fits the isotherm data best, with the highest R 2 value of 0.996.…”

“…where K F -the coefficient of distribution or adsorption coefficient (L/g). The Temkin isotherm model takes into account the adsorbate-adsorbent interaction and assumes that the heat of the adsorption of all the molecules in the layer will decrease linearly as adsorbed molecules accumulate on the surface of the adsorbent [35]. The isotherm was calculated according to Equation (7).…”

Within this study, aluminum oxide granules with 0.25%vol. of graphene oxide were prepared by a spray-drying method to make an adsorbent for the 2,4-Dichlorophenoxyacetic acid (2,4-D) herbicide removal from aqueous solutions. The obtained adsorbent was studied using infrared spectroscopy, scanning electron microscopy and Raman spectroscopy. The presence of graphene in the spray-dried powder was confirmed. The adsorption removal of 2,4-D using the obtained material was performed at an ambient temperature by varying the process parameters such as pH and adsorption time. The adsorption of 2,4-D was a monolayer chemisorption according to the Langmuir isotherm pattern and a pseudo-second-order kinetic model. The maximum Langmuir adsorption capacity of the monolayer was 35.181 mg/g. The results show that the Al2O3-0.25%vol. GO powder obtained by spray drying is suitable for the production of adsorbents for toxic herbicides.

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.

“…These membranes are usually targeted towards softening of water, being partially effective in removing dissolved ions [19]. Previous studies have reported pesticide removal e ciencies ranging from 30.00% to greater than 90.00% for phenylurea, phenoxyacetic acid, triazines, dithiolane pesticides organophosphate or synthetic auxin classes [20][21][22][23][24]. Meanwhile, reverse osmosis membranes have a molecular cut-off smaller than 100 Da [25] and are the standard on desalination processes.…”

The increasing food demand for a growing population has resulted in the intensification and modernization of agriculture leading to an increasing use of pesticides to protect crops against insects, weeds, fungi, and other pests. However, these chemical compounds can cause adverse effects on the environment due to their low biodegradability and toxicity. This study assesses the use of DuPont FilmTec™ NF270 and FilmTec™ XLE membranes for the removal of six pesticides (atrazine, simazine, isoproturon, metolachlor ESA, 2,4-D, and chlorothalonil) in aqueous streams. The results reported average rejection rates of 29.25–89.36% and > 97% in the nanofiltration and reverse osmosis membranes respectively, showcasing that membrane technology is effective for the removal of these pollutants from wastewater streams. However, a customised selection of the membrane (nanofiltration/reverse osmosis) should be performed depending on the targeted pollutants in order to balance the pesticide rejection and energy consumption for each market application.
