“…In its natural state, crude PS has shown promise as an adsorbent for pesticides such as atrazine (Saha et al, 2017), 2,4‐D (Demirhan et al, 2018), and nitenpyram (Chen et al, 2019) from aqueous solution. Moreover, the high adsorption capacity of PS can be associated with the presence of micropores and the high interaction between the adsorbent and the adsorbate, highlighting its potential as a green material with a focus on the adsorption capacity of OC compounds such as 2,4‐D (Demirhan et al, 2018; Orduz et al, 2021). Demirhan et al (2018) concluded that the amount of adsorbed 2,4‐D increased with increasing 2,4‐D concentration (from 10 to 50 mg L −1 ) in the initial solution.…”

“…In addition to being used as an adsorbent for pesticides, PS can also be used as an attractive AC precursor due to the abundant cellulose and polymer material (Demirhan et al, 2018; Trivedi et al, 2019; Wang, Nam, et al, 2020). The use of AC from peanut shells as an adsorbent for the extraction and enrichment of 2,4‐D was recently demonstrated (Orduz et al, 2021). Here, the adsorption process was studied with two main objectives: Reuse of the material and pre‐concentration for better quantification of the target analyte.…”

Despite their high persistence in the environment, organochlorines (OC) are widely used in the pharmaceutical industry, in plastics, and in the manufacture of pesticides, among other applications. These compounds and the byproducts of their decomposition deserve attention and efficient proposals for their treatment. Among sustainable alternatives, the use of ligninolytic enzymes (LEs) from fungi stands out, as these molecules can catalyze the transformation of a wide range of pollutants. Among LEs, laccases (Lac) are known for their efficiency as biocatalysts in the conversion of organic pollutants. Their application in biotechnological processes is possible, but the enzymes are often unstable and difficult to recover after use, driving up costs. Immobilization of enzymes on a matrix (support or solid carrier) allows recovery and stabilization of this catalytic capacity. Agricultural residual biomass is a passive environmental asset. Although underestimated and still treated as an undesirable component, residual biomass can be used as a low‐cost adsorbent and as a support for the immobilization of enzymes. In this review, the adsorption capacity and immobilization of fungal Lac on supports made from residual biomass, including compounds such as biochar, for the removal of OC compounds are analyzed and compared with the use of synthetic supports. A qualitative and quantitative comparison of the reported results was made. In this context, the use of peanut shells is highlighted in view of the increasing peanut production worldwide. The linkage of methods with circular economy approaches that can be applied in practice is discussed.

“…Orduz et al [79] investigated the 2,4-D adsorption by activated carbon from peanut shells (steam activation, S BET = 1240 m 2 g −1 ) in aqueous and organic solvents. The pollutant desorption kinetics and the application of the AC as a filler in a solid-phase extraction procedure (SPE) were presented.…”

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.

“…9 Among them, adsorption has been employed as a low-cost and efficient technique to remove 2,4-D with low concentrations at large volumes. [10][11][12][13] In recent years, various adsorbents have been developed to remove organic pollutants from wastewater. As a porous material, activated carbon is widely used as an adsorbent in water treatment.…”
