“…When the pH of the aqueous solution was increased from 3 to 11, the removal efficiency of the chlorpyrifos decreased from 100 to 93%. The removal rate changes of OPPs for different pH levels had a similar pattern with the trend reported in previous works (Gupta et al, 2002;Moussavi et al, 2013;Kumar et al, 2014;Naushad et al, 2014). The adsorption mechanism of OPP compounds onto the Fe 3 O 4 /red mud-NPs can be explained by electrostatic interaction.…”

“…Adsorption onto activated carbon is the most widely used technique for the removal of a number of toxic pollutants from water. However, due to high operation and investment costs of this technique, new inexpensive adsorbent materials have been developed in order to remove organic contaminants from water Kumar et al, 2014;Pal and Vanjara, 2001). Taha et al (2014) used untreated and treated biochars and charcoal in order to treat contaminated water with 15 different pesticides including diazinon and malathion.…”

“…In another study, sunflower seed shells, rice husk, composted sewage sludge, and soil were used for the development of low-cost pesticide decontamination techniques (Rojas et al, 2014). The usability of rice husk, activated rice husk, and bagasse fly ash were investigated for the removal of malathion from aqueous solution (Gupta et al, 2002;Kumar et al, 2014). Memon et al (2008) used watermelon peels as a low cost adsorbent for adsorption of methyl parathion from water.…”

The aim of this study was to investigate the usability of magnetic Fe3O4/red mud nanoparticles (NPs) for the removal of organophosphorus pesticides from water samples. The effect of various experimental parameters such as red mud amount in Fe3O4/red mud-NPs, pH, contact time, initial pesticide concentrations and adsorbent dose was studied in order to find the optimum conditions for their removal in a batch process. The Fe3O4/red mud-NPs were characterized by using TGA, SEM, XRD, VSM, and determination of the BET surface area. After the regenerated Fe3O4/red mud-NPs were used three times, the sorption capacity and the magnetic separability were observed to be unaffected. Freundlich model described the sorption process better than Langmuir isotherm and the pseudo second-order kinetic model was determined as the best-fit model. The film diffusion mechanism was found to be a main rate control mechanism. The Fe3O4/red mud-NPs satisfactorily removed the OPPS from real water samples.

“…Among these conventional methods for the removal of pesticides, adsorption technique is found to be the most economical, effective, highly flexible in design, and simple as well as offers scope for regeneration of adsorbent materials [3]. Therefore, adsorption technique has drawn wide attention of the investigators for the removal of pesticides from contaminated water samples [16][17][18][19][20]. In this perspective, intense research interest has been generated for exploring cost-effective, ecofriendly, and easily available adsorbent particularly of biological origin [16][17][18][19][20][21][22][23].…”

“…Previously, neem bark dust (NBD) had been used effectively to remove many pollutants like Zn(II) and Cd(II) [30,31], Cr(VI) [32], As(III) [20], and dyes [33][34][35] from aqueous solutions, but no such information has been reported on the removal of carbaryl by NBD. Thus, to find the higher value of adsorption capacity compared to other adsorbents, NBD was chosen to remove carbaryl insecticide from aqueous solutions.…”

Adsorptive removal of carbaryl from aqueous solutions by neem bark dust (NBD) was investigated in a batch method under laboratory conditions. At first, the effects of particle size, stirring rate, and contact time on the adsorption process were studied. The optimum value of particle size, stirring rate, and contact time were 200 μm, 250 rpm, and 25 min, respectively. Subsequently, response surface methodology (RSM) was applied to investigate the effects of other operating parameters such as solution pH (2-10), adsorbent dose (0.01-1 g), and initial concentration (5-20 ppm). The optimization of the process parameters and calculation of the effects and interactions of process variables were done by using Box-Behnken design (BBD) which is a subset of RSM. The independent variables were precisely optimized by making use of an objective function called Bdesirability function.^Based on the adsorption capacity and economical use of adsorbent, the input parameters were optimized by setting two different sets of criteria (I and II). The desirability of two different sets were 1.00 and 0.822, respectively, which explains that the estimated function can well represent the experimental model. The optimized result revealed that the NBD can be an effective adsorbent for the removal of carbaryl from an aqueous system. The adsorption of carbaryl on NBD was best analyzed with the Langmuir isotherm and the pseudo-second order kinetic model. From the kinetic study, the maximum adsorption capacity was found to be 142.85 mg g −1 . Thermodynamic data confirmed the feasibility and spontaneous nature of the adsorption process.

Nations (FAO) estimates that approximately 40% of food crops are lost each year to plant pests and diseases. [2] These losses result in a shortfall in crop yields for sufficient food production, causing significant economic consequences. [1,2] Over the years, various anthropogenic activities, together with climate change, have led to alterations in ecosystems that cause considerable damage in areas such as agriculture. The reduction in biodiversity and the creation of new niches are some of these effects that allow, among other things, the rapid spread of pests. [1,2] Therefore, plant protection in agricultural crops is crucial for avoiding the impacts caused by devastating pests and diseases.Agricultural activities face the dual challenges of, on the one hand, becoming more productive and, on the other hand, reducing their impacts on the environment as much as possible. In the case of the former, the use of chemical products such as pesticides is often essential for the control of crop diseases and pests, [2][3][4] improving crop yields and providing greater food security for society. However, although the use of pesticides brings important benefits, including reduced crop damage and, consequently, increased food quality and quantity, these substances have detrimental effects on the environment. [5][6][7] One of the negative effects of the use of chemical pesticides in agricultural systems is the impact on water resources, [1,7] depending on factors including the nature of the compound used, the mode of application, and climatic variations. [1,7] The low degradability of pesticides enables them to accumulate in the soil or to be transported to surface water and groundwater, causing further environmental damage. Although the soil is the main receptor medium for these chemicals, water resources including rivers, streams, lakes, and groundwater are highly susceptible to contamination, due to the interconnection between water bodies and soil. The persistence of these compounds resulting from agricultural practices in hydrographic basins is a threat to human health. [1,4,7] Contamination of groundwater by pesticides and their residues is recognized as a problem in both advanced and developing countries. [2,8] Consequently, the scientific community faces a continuous challenge to develop suitable materials, together with new and more efficient technologies, for the
