Magnetism in low-dimensional carbon materials, which is crucial for the realization of the physical properties, potential application, and development of carbon-based spintronic devices, has attracted extensive attention. In this Review, three typical low-dimensional carbon materials, including carbon nanotubes, graphene, and graphdiyne, are used to exhibit the research progress of a magnetic two-dimensional (2D) carbon material preparation strategy, the introduction of the local magnetic moment, and the resulting unique magnetic properties. The convenient and facile preparation methods of carbon-based magnetic materials have been introduced on the basis of their structural characteristics, especially for the advantageous structures and efficient chemical modification in graphene and graphdiyne. Various interesting ways, such as transition metal atom doping and nonmetal atom modification, have been exhibited to tune the electromagnetic characteristics of carbon-based materials. All those research studies provide a theoretical basis to promote the application of 2D carbon-based magnetic materials in spintronic devices involving spin and charge modulation and lay a foundation for the preparation of high-performance carbon-based magnetic materials with specific magnetic properties.

“…Atrazine has the characteristics of a stable structure, a long half-life (8-52 weeks) and difficult degradation. It can exist in water for a long time and has an impact on aquatic organisms and the human body [5]. The main degradation products of atrazine are de-ethyl atrazine, de-isopropyl atrazine and hydroxyatrazine, and the first two have similar toxicity to atrazine [6].…”

In this study, the preparation of apricot kernel shell biochar by a hydrothermal method and its adsorption mechanism for atrazine was studied by scanning electron microscopy (SEM) and infrared spectrum (FTIR) analytical techniques. The results show that the biochar prepared from the apricot kernel shell has an evenly distributed, nonaggregated carbon microsphere structure and contains a large number of oxygen-containing groups. The higher the preparation temperature is, the more functional groups exist and the better the potential adsorption performance is. The adsorption kinetics of atrazine on apricot kernel shell biochar were fitted with a quasi-second-order kinetic equation (R2 ≥ 0.995, p < 0.05). The isothermal adsorption data were in accordance with the Freundlich model (R2 ≥ 0.911, p < 0.05). The adsorption of atrazine on apricot kernel shell biochar includes two processes: surface adsorption and diffusion. The adsorption capacity of apricot kernel shell biochar for atrazine increases with increasing preparation temperature and decreases with increasing pH and Ca2+ concentration. The adsorption mechanism includes hydrogen bonding and hydrophobic interactions. Therefore, biochar prepared from apricot shells, an agricultural waste, exhibits good adsorption performance for atrazine and has a good application prospect in addressing agricultural non-point source pollution, especially in pesticide residue pollution control.

“…For example, graphene oxide (GO) is a useful single atomic layered carbon compound that can be a potent substance for the adsorption and extraction methods due to its large specific surface area. Therefore, using GO in the pre-concentration, extraction, and microextraction procedures can efficiently improve their performance [ 25 ]. In addition, deposition of metal (M) or metal oxides (MO), such as three-dimensional transition metal oxides (3D-TMO), metal–organic frameworks (MOFs), and nano-crystalline mixed metal oxides (MMO), on the fiber substrate have developed many new SPME fibers [ 26 , 27 ].…”

Background Solid-phase microextraction (SPME) is a versatile sampling and sample preparation technology that possess a significant application in the extraction and pre-concentration of a broad range of micro-pollutants from different kind of matrices. Selection and preparation of an appropriate fiber substrate and coating materials have always been the main challenges of the SPME procedure. This paper introduces a high-efficiency metal-based SPME fiber with a new chemical coating of nickel/graphene oxide/nickel tetraazamacrocyclic complex (Ni/GO/NiTAM). Result The Ni/GO/NiTAM sorbent was electroless deposited onto the surface of an aluchrom (Alu) wire, and then the prepared fiber was employed for the extraction and pre-concentration of some PAHs before their HPLC–UV analysis. The prepared fiber characterization data were assessed using FE-SEM, EDX, XRD, FT-IR, and BET techniques. The method validation parameters, including the linearity range (LRs: 0.10 to 200.0 µg L−1), the limit of detection (LODs: 0.03‒0.30 µg L−1), and the limit of quantification (LOQs: 0.10–1.00 µg L−1), under optimal conditions. The relative standard deviations (RSDs) of intra-day, inter-day, and single fiber repeatability (for the samples spiked at 25 µg L‒1) were in the range of 0.32–2.94, 1.20–4.09, and 1.42‒4.39%, respectively. In addition, the technique recoveries (RR %) and enrichment factors (EF) were in the range of 83.10‒107.80% and 83–164, respectively. Conclusion The fiber fabrication was simple, and the applied materials were also economical and easily accessible. Alu metal has high physicochemical and mechanical stability and thus can be a good alternative for the substrate of the fragile commercial SPME fibers. High rigidity and durability, long service life, and high extraction capability are some of the other advantages of the offered fiber.
