“…In studies of pharmaceuticals adsorption in river sediment samples, it was shown that the sorption of carbamazepine and diclofenac was higher than for ibuprofen, namely KD for CBZ was in the range of 5.57-24.55 L kg −1 and KD for DIC was 4.04-33.01 L kg −1 [55]. Similar results were also obtained for soil samples collected from dam reservoirs, where KD of CBZ was 2.9-5.5 L kg -1 , and 4.8-5.5 L kg −1 for DIC [20], and in tropical soil samples CBZ was 0.83-3.38 L kg −1 [56].…”

The increase in the production and consumption of pharmaceuticals increases their presence in the global environment, which may result in direct threats to living organisms. For this reason, there is a need for new methods to analyze drugs in environmental samples. Here, a new procedure for separating and determining selected drugs (diclofenac, ibuprofen, and carbamazepine) from bottom sediment and water samples was developed. Drugs were determined by ultra-high performance liquid chromatography coupled with an ultraviolet detector (UHPLC-UV). In this work, a universal and single-step sample treatment, based on supramolecular solvents (SUPRAS), was proposed to isolate selected anticonvulsants and nonsteroidal anti-inflammatory drugs (NSAIDs) from sediment samples. The following parameters were experimentally selected: composition of the supramolecular solvent (composition THF:H2O (v/v), amount of decanoic acid), volume of extractant, sample mass, extraction time, centrifugation time, and centrifugation speed. Finally, the developed procedure was validated. A Speedisk procedure was also developed to extract selected drugs from water samples. The recovery of analytes using the SUPRAS procedure was in the range of 88.8–115%, while the recoveries of the Speedisk solid-phase extraction procedure ranged from 81.0–106%. The effectiveness of the sorption of the tested drugs by sediment was also examined.

“…Khazri and co-workers have recently showed that natural clay, a mixture of smectite-kaolinite and quartz, can efficiently remove ibuprofen with a maximum adsorption capacity of 37 mg.g −1 (Khazri et al, 2016). Based on their adsorption isotherm and IR data, authors also suggest that anionic or neutral PPCPs, i.e.…”

Abiotic degradation and environmental toxicity of ibuprofen: Roles of mineral particles and solar radiation

et al. 2018

The growing medical and personal needs of human populations have escalated release of pharmaceuticals and personal care products into our natural environment. This work investigates abiotic degradation pathways of a particular PPCP, ibuprofen, in the presence of a major mineral component of soil (kaolinite clay), as well as the health effects of the primary compound and its degradation products. Results from these studies showed that the rate and extent of ibuprofen degradation is greatly influenced by the presence of clay particles and solar radiation. In the absence of solar radiation, the dominant reaction mechanism was observed to be the adsorption of ibuprofen onto clay surface where surface silanol groups play a key role. In contrast, under solar radiation and in the presence of clay particles, ibuprofen breaks down to several fractions. The decay rates were at least 6-fold higher for irradiated samples compared to those of dark conditions. Toxicity of primary ibuprofen and its secondary residues were tested on three microorganisms: Bacillus megaterium, Pseudoaltermonas atlantica; and algae from the Chlorella genus. The results from the biological assays show that primary PPCP is more toxic than the mixture of secondary products. Overall, however, biological assays carried out using only 4-acetylbenzoic acid, the most abundant secondary product, show a higher toxic effect on algae compared to its parent compound.

“…Analysis of the experimental data suggest that adsorption of ibuprofen can be realized in a wide range of pH, what is determined mostly by the type of the sorption material used. More acidic environment is the most suitable when adsorbing ibuprofen onto activated carbons (Maestre et al 2007;Guedidi et al 2017) as neutral or basic are better one to adsorb it onto natural clays (Martín et al 2019;Rafati et al 2018;Khazri et al 2017). Comparison of maximum sorption capacities of different type sorbents confirmed that the most important is appropriate selection of the material.…”

The aim of presented research concerned synthesis of a novel lignosulfonate-based sorbent and its application in batch adsorption tests related to removal of an active pharmaceutical ingredient (ibuprofen). Obtained hybrid material was thoroughly characterized with respect to morphology, porosity (BET method and BJH algorithm), electrokinetic stability, and characteristic functional groups. As a result of the proposed synthesis route, an active MgO-SiO 2 /lignosulfonate hybrid was obtained as confirmed by significant amount of functional groups present in its structure and relative good parameters of the porous structure (A BET = 71 m 2 /g, V p = 0.2 mL/g and S p = 11.8 nm). Next stage concerned typical batch adsorption tests with respect to active pharmaceutical ingredient (API)-ibuprofen. It was proved that efficiency of removal of ibuprofen was mostly determined by its structure as well as variable process parameters. Affinity of sorption material towards model organic impurity was established based on equilibrium and kinetics study of adsorption process performed. A key element of the investigations was an interaction and mechanism study resulted from interpretation how the parameters of the adsorption affect the nature of the adsorbent/adsorbate interactions. Experimental data collected, supplemented with regeneration tests, proved significant affinity of ibuprofen to the hybrid sorbent and enabled determination of nature of the adsorbent/adsorbate interactions. Moreover, suggested mechanism of ibuprofen sorption was proposed.
