“…In the recent past, several sewage sludge based adsorbents have been used for the removal of pollutants from aqueous solutions as reported in literature [115,116,117]. Sewage sludge based adsorbents have been produced by different chemical activation methods [118,119] which were then used for the adsorption of phenols, metals and dyes from wastewaters.…”

“…Results showed that wine processing waste sludge can be used as an adsorbent for the effective removal of Cr(III) from aqueous solution. Gupta and Garg [117] examined the performance of sewage sludge based adsorbents or the removal of two recalcitrant pollutants (i.e. lignin and amoxicillin) from synthetic wastewater solutions (adsorbate concentration = 50-250 mg/l).…”

Low-cost by-products from agricultural, household and industrial sectors have been recognized as a sustainable solution for wastewater treatment. They allow achieving the removal of pollutants from wastewater and at same time to contribute to the waste minimization, recovery and reuse. Despite numerous reviews have been published in the last few years, a direct comparison of data obtained using different sorbents is difficult nowadays because of inconsistencies in the data presentation. In this context, the aim of the study was to revise the current literature concerning the application of low-cost adsorbents for wastewater treatment highlighting, systematically, both adsorbents characteristics and adsorption capacities. For this scope, low-cost sorbents have been divided into the following five groups: (i) Agricultural and household wastes, (ii) industrial by-products, (iii) sludge, (iv) sea materials, (v) soil and ore materials and (vi) novel low-cost adsorbents. The affinity of sorbents in removing various pollutants, their applications on real wastewater, costs and considerations on their reuse after adsorption processes, has been discussed. Finally, in order to better highlights the affinity of sorbents for more pollutants (dyes, heavy metals, biorecalcitrant compounds, nitrogen and phosphate compounds), simple methodological tools such as "adsorbentspollutants" matrices have been proposed and applied. In this manner, the adsorbent candidates for

“…It could be seen that the experimental data were fitted better by the Freundlich and Dubinin–Radushkevic isotherms ( R 2 > 0.98). The parameters k F and n in the Freundlich isotherm showed a relatively high capacity and a strong adsorption strength between the HNF‐PDVB and diesel oil in water, as the value of Freundlich constant n was in the range of 1 < n < 10 . The Dubinin–Radushkevic isotherm model gave information on whether the adsorption involved intraparticle diffusion .…”

Background Oil pollution of water causes extensive damage to the environment and human health. Adsorption techniques are environmentally friendly and relatively feasible to treat oil contamination and reclaim oil resources, and it is essential to develop adsorbents that have high adsorption capacity for oil which can be recycled and regenerated conveniently to save money and resources. Results Hydrophobic nonwoven fabrics coated with polydivinylbenzene nanofibres (HNF‐PDVB) were constructed by a one‐step cation polymerization reaction. The results showed that the optimal concentration of OTS (octadecylsilane) for the modification of nonwoven fibers was 1.22 mL L–1of n‐hexane. The HNF‐PDVB showed relatively good performance in adsorbing oil from water, with adsorption capacity as high as 7.5 g g–1. Freundlich and Dubinin–Radushkevic isotherms fitted well with the experimental data. The kinetic data fitted better to the pseudo‐second‐order and intraparticle diffusion models, and the parameters indicated that the adsorption by HNF‐PDVB involved macropores that contributed to the rapid and high‐capacity adsorption, as well as micropores that resulted in the diffusion of oil in the nanofibres. Thermodynamics studies revealed that the adsorption was spontaneous and endothermic, with an increasing performance when the temperature rose from 10 to 50 °C. The material possessed good stability and the adsorption capacity reduced from 7.5 g g–1 to 6.6 g g–1 after ten cycles of repeated use, recovered by squeezing and ethanol extraction. Conclusion This work demonstrates that the new hydrophobic nonwoven fabrics have the potential to be used for elimination of pollution from oil wastewater. © 2018 Society of Chemical Industry

In this paper, biodegradable polycaprolactone (PCL) was used as the raw material to prepare micro/nanofibrous polycaprolactone membrane (PCLM) through solution blow spinning (SBS) technology. The effects of spinning conditions (distance, gas pressure, and spinning solution concentration) on PCLM structures were investigated. The obtained membranes were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy, water contact angle, and thermogravimetric analysis instrument. The oil adsorbency and reusability of PCLM were measured. The oil adsorption capacity of PCLM for motor oil, peanut oil, and diesel oil was 15.93, 14.81, and 12.86 g·g−1, respectively. After 10 times of reuse, the adsorption capacity for motor oil, peanut oil, and diesel oil could still remain at about 80% of the first cycle. The kinetic and thermodynamic studies showed that the adsorption conformed to the first‐order kinetic model and Freundlich model. Thermodynamic parameters for oil adsorption ΔGθ, ΔHθ, and ΔSθ indicated the oil adsorption of PCLM was a spontaneous and physisorption process.
