“…17 Biochar can be prepared from a variety of industrial and agricultural organic wastes, such as sewage sludge, animal manure, crop straw, and other plant or animal waste. [18][19][20][21] Due to its low cost, wide range of raw material, superior surface properties and rich functional groups, biochar can be used as a potential sorbent to remove many kinds of heavy metal pollutants like Cd, As, Pb and organic pollutants in water. [22][23][24][25] Our previous study indicated that biochar produced from wheat straw had a good adsorption capacity for Cd(II).…”

“…In particular, with readily availability and low cost of materials, the adsorption effect of activated carbons (ACs) on natural organic compounds, metal ions, and synthetic organic matter is very effective [8,9]. ACs can be easily obtained from different agricultural by-products such as nuts, wheat, straw, soybeans, corn stover, and wood [10,11,12,13]. Therefore, pollutants removal through the adsorption onto ACs is an effective method.…”

Activated carbons (ACs) based on apricot shells (AS), wood (W), and walnut shells (WS) were applied to adsorb atrazine in co-solutions. To study the effect of Bisphenol A (BPA) on the adsorption behavior of atrazine, the adsorption performance of ACs for BPA in single solution was studied. The results demonstrated that the adsorption kinetics of BPA fitted the pseudo-second-order model, the adsorption isotherms of BPA followed the Langmuir model. Meanwhile, the adsorption kinetics of atrazine fitted the pseudo-second-order kinetics model and the isotherm was consistent with the Freundlich model both in single solution and co-solution. In addition, competitive adsorption was observed when atrazine coexisted with BPA or humic acid. For the adsorption capacity, the adsorption amount of ASAC, WAC, and WSAC for atrazine obviously decreased by 18.0%, 30.0%, and 30.3% in the presence of BPA, respectively, which was due to the π−π interactions, hydrophobic interactions, and H-bonds, resulting in the competitive adsorption between atrazine and BPA. This study contributes to the further understanding of the adsorption behavior for atrazine in co-solution.

“…One of the main strategies for removal of pesticides from water is the adsorption on different types of materials [5]. Numerous studies can be found in the literature reporting OPs adsorption on mineral surfaces [6,7], carbon-based materials [8][9][10], and materials from graphene family [11]. Nowadays, application of nanoparticles (NPs) in environmental remediation such as water purification by removal of OPs is significantly progressing because of nanomaterial chemistry advantages with respect to conventional technologies [1,12].…”

Organophosphorus pesticide dimethoate was adsorbed onto gold nanospheres and nanorods in aqueous solution using batch technique. Adsorption of dimethoate onto gold nanoparticles was confirmed by UV-Vis spectrophotometry, TEM, AFM, and FTIR analysis. The adsorption of nanospheres resulted in aggregation which was not the case with nanorods. Nanoparticles adsorption features were characterized using Langmuir and Freundlich isotherm models. The Langmuir adsorption isotherm was found to have the best fit to the experimental data for both types of nanoparticles. Adsorption capacity detected for nanospheres is 456 mg/g and for nanorods is 57.1 mg/g. Also, nanoparticles were successfully used for dimethoate removal from spiked drinking water while nanospheres were shown to be more efficient than nanorods.

Preponderant adsorption for chlorpyrifos over atrazine by wheat straw-derived biochar: experimental and theoretical studies

Abstract: In competitive sorption, WS750 prefers to adsorb chlorpyrifos over atrazine since that chlorpyrifos has stronger pi–pi interaction with WS750 (23.68 kcal mol−1) and larger lipophilicity (log P= 4.7) than that (22.70 kcal mol−1, log P= 2.7) of atrazine.
