“…A clear linear correlation can be realized between the adsorption capacity and the initial CPH concentration. The adsorption capacity increases proportionally with concentration, most likely due to a decrease in the mass transfer resistance resulting from the higher concentration gradient as previously reported [18]. Adsorption capacities of 37, 33, and 32 mg/g corresponding to 3027, 2660, and 2578 mg/m 2 , for the Co, Cu, and Ni-loaded membranes, respectively, were obtained at 50 ppm of CPH, as opposed to 29 mg/g (2324 mg/ m 2 ) and 28 mg/g (2317 mg/m 2 ) pertaining to non-porous and porous membranes, respectively.…”

The antibiotic Ciprofloxacin HCl (CPH) is a representative example of pharmaceutical contaminants of emerging concern that are frequently released in wastewater effluents and can cause hazardous health effects. In this work, we investigated the potential of utilizing porous polymeric membranes incorporating metal nanoparticles for removing CPH from water. In this regard, polylactic acid/polyurethane membranes were impregnated in situ with single, binary, and tertiary systems of nanoparticles of cobalt, copper, and nickel, among others. Membranes loaded with cobalt exhibited the best performance among all the examined membranes. They yielded removal efficiencies above 80% at an initial CPH concentration range of 10–50 ppm and pH 6.5, thus exceeding those of the bare membranes by about 1.3 times under the same conditions. As confirmed by Brunauer, Emmet, and Teller (BET) analysis, the incorporation of cobalt nanoparticles into the mesoporous membranes increased their surface area and pore volume by 5 and 10 times, respectively. Thermogravimetric analysis (TGA) showed that cobalt nanoparticles had no catalytic influence on the dissociation of the membrane polymeric chains. Fourier transform infrared (FTIR) and zeta potential measurements suggested that binding could possibly occur via physical interactions along with catalytic degradation.

Poly(β-cyclodextrin)-Activated Carbon Gel Composites for Removal of Pesticides from Water

et al. 2021

Pesticides are widely used in agriculture to increase and protect crop production. A substantial percentage of the active substances applied is retained in the soil or flows into water courses, constituting a very relevant environmental problem. There are several methods for the removal of pesticides from soils and water; however, their efficiency is still a challenge. An alternative to current methods relies on the use of effective adsorbents in removing pesticides which are, simultaneously, capable of releasing pesticides into the soil when needed. This reduces costs related to their application and waste treatments and, thus, overall environmental costs. In this paper, we describe the synthesis and preparation of activated carbon-containing poly(β-cyclodextrin) composites. The composites were characterized by different techniques and their ability to absorb pesticides was assessed by using two active substances: cymoxanil and imidacloprid. Composites with 5 and 10 wt% of activated carbon showed very good stability, high removal efficiencies (>75%) and pesticide sorption capacity up to ca. 50 mg g−1. The effect of additives (NaCl and urea) was also evaluated. The composites were able to release around 30% of the initial sorbed amount of pesticide without losing the capacity to keep the maximum removal efficiency in sorption/desorption cycles.

“…Therefore, seeking an efficient and low-cost method for its remediation is a major concern for environmental issues. Among the applied method for remediation of pesticides, adsorption is still the most applied methods due to its effectiveness, simplicity, and low-cost method (Maneerung et al, 2016;Mohammad and El-Sayed, 2021). Many recent studies focused on using activated carbon derived from agricultural wastes, and clay minerals are pesticide removal from polluted water (Liu et al, 2015;Tran et al, 2015;Mojiri et al, 2020).…”

This study investigated the removal of imidacloprid (IMI) and oxamyl (OX) pesticides by cement kiln dust (CKD) as industrial by-products. CKD was identified by elements composition, Fourier-transform infrared (FTIR), and scanning electron microscopy (SEM). Effects of initial concentration (100-2000 mg/L), and contact time (10-360 min) were investigated. The kinetic results of IMI and OX pesticides were fitted to pseudo-first-order, pseudo-secondorder, and intra-particle diffusion equations. The pseudosecond-order kinetic model fitted well for IMI removal, while pseudo-first-order kinetic model flitted to OX removal results. Isotherm results were examined by different isotherm models (Freundlich, Langmuir, and Temkin equations). The results fitted well with the Langmuir isotherm model (R 2 =0.988 and 0.999) with maximum adsorption capacity of 142.85 and 100.00 mg/g for IMI and OX pesticide removal by CKD, respectively. The obtained results indicated the potential of using CKD as an efficient and, low-cost adsorbent for the removal of IMI and OX pesticides from aqueous solutions.
