“…Particularly, carbon black (CB) is an important carbon-based nanomaterial from the industrial point of view with more than 8.1 million metric tonnes produced worldwide . Thus, to monitor CB in the environment and study its behavior and adverse effects, methods to extract CB from soils, sediments, and biota are required as well as methods to further characterize CB from such complex samples. − …”

In the present work, a procedure based on a dispersive medium for carbon black (CB) isolation from soil samples for analysis was proposed for the first time. Polymeric and biological dispersants and a sequential use of both dispersants were assayed. Asymmetrical flow field flow fractionation with dynamic light scattering detector (AF4-DLS) and sedimentation field flow fractionation with multi-angle light scattering detector (SdF3-MALS) were used for CB quantitation and characterization in the achieved dispersions. Soil samples contaminated with CB were processed, and CB isolation depended on the solid size distribution and composition and dispersant nature. More quantitative isolations were achieved for the four soils treated by the biological dispersant. As the organic matter percentage is higher in soil, the CB isolation was better, varying between 75 and 99% with standard deviation (s) ⩽ 2% for all soils. A soil contaminated with a CB-based pigment paste was analyzed, achieving (99 ± 2)% expressed as expanded uncertainty ( K = 2) of dispersive isolation by the biological dispersant, and the sampling was scaled to 250 g of soil with positive results. The procedure was completed by CB recovery to obtain a solid residue able to be reused if necessary. For the filter-aided recovery step, different membranes (fiberglass, nylon, and Teflon) with a pore size between 0.1 and 5 μm were tested. The quantitation of the CB retained in the filter was measured by diffuse reflectance spectroscopy. Teflon (0.10 μm) provided better results for CB recovery, and its re-dispersion was also studied with suitable results. Determination of CB from the filters by diffuse reflectance spectrometry provided the same results than AF4 for CB dispersions.

“…In addition, CBN is cheaper than other carbon materials such as carbon nanotubes and graphene, which has allowed it to be widely applied as sorbent material 8,9 and for the development of low-cost electrochemical sensors 10,11 . The main difference between CB and black Carbon (elemental Carbon) is the lower content of extractable organic and inorganic compounds (less than 1%) 12 .…”

The growing development of Nanotechnology has allowed the synthesis and characterization of nanomaterials with peculiar physicochemical properties. These nanomaterials have been applied in various scientific and industrial sectors. The present study established the synthesis of carbon black agglomerates (CBA) from waste vegetal materials as a source of renewable raw materials using a simple, fast, and effective procedure. Once this nanostructured material was obtained, several analytical techniques were applied to establish its main characteristics, including X-ray diffraction, Fourier transform infrared spectroscopy, Brunauer–Emmett–Teller (BET) theory analysis, and SEM imaging. The results of this characterization have made it possible to establish that these materials have properties that make them suitable for application as extracting sorbents in microextraction sample treatment techniques under the green analytical chemistry approach. In this study, we applied Pipette-tip SPE microextraction for pharmaceutical compound extraction studies, preparing extraction devices with less than five milligrams of the sorbent. The results showed high extraction percentages for compounds such as paracetamol, caffeine, diazepam, and dexamethasone. Finally, an application example of the last compound is presented, developing a procedure for its determination in urine samples by high-performance liquid chromatography with diode array detection (HPLC-DAD) chromatographic analysis with high merit figures in terms of simplicity, high extraction efficiency, and environmental friendliness.

Insufficient homogeneity is one of the pressing problems in nanocomposites’ production as it largely impairs the properties of materials with relatively high filler concentration. Within this work, it is demonstrated how selected mixing techniques (magnetic mixer stirring, calendaring and microfluidization) affect filler distribution in poly(dimethylsiloxane)-graphene based nanocomposites and, consequently, their properties. The differences were assessed via imaging and thermal techniques, i.a. Raman spectroscopy, differential scanning calorimetry and thermogravimetry. As microfluidization proved to provide the best homogenization, it was used to prepare nanocomposites of different filler concentration, whose structural and thermal properties were investigated. The results show that the concentration of graphene significantly affects polymer chain mobility, grain sizes, defect density and cross-linking level. Both factors considered in this work considerably influence thermal stability and other features which are crucial for application in electronics, EMI shielding, thermal interface materials etc.
