Special Issue Information

Dear Colleagues,

Water is a vitally important compound for human life. About 60% of the human body is water. Without water, animal, plant and human cannot survive. The quantity of drinkable water is extremely limited. The proportional increase in industrial, agricultural and domestic activities arising from the growing human population has led to elevated levels of hazardous chemicals such as synthetic dyes, phenols, pesticides, heavy metals and pharmaceutical residues, in the environment over the years. Such pollutants have been reported to cause toxicosis accumulation and carcinogenic effects on human beings. Different strategies have been developed for water remediation to make it clean and reusable, and to meet the increasing demands of fresh water.

The development of nanotechnology provides a promising alternative to enhance the treatment efficiency. Nanomaterials (NMs) have unique physical and chemical properties such as large surface area, surface activity and specific affinity. Therefore, NMs have attracted significant interest for the detection and removal of inorganic and organic pollutants from water. As a result, the advance development of nanotechnology and NMs offer advancing opportunities for water treatment and environmental sustainability.

In this special issue, we intend to invite front-line researchers and authors to submit original research and review articles on the applications of nano-based materials for the environmental remediation.

Fe–Mn binary oxide nanoparticles (FMBON) were reported to be high performance as adsorbent for pollutants removal from aqueous solution. However, there are still limitations in practice application due to the FMBON tend to aggregate into the micro millimeter level. In order to avoid the agglomeration of nanoparticles, this work synthesized the stabilized Fe–Mn binary oxide nanoparticles (CMC-FMBON) by using water-soluble carboxymethyl celluloses (CMC) as the stabilizer. The characteristics of CMC-FMBON and FMBON were measured by using Transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and Zeta potential. This work systematically investigated the adsorption capacity of CMC-FMBON for 17β-estradiol (E2) and the influences of external environmental factors on E2 removal. The results indicated that CMC-FMBON had much smaller particles, wider dispersion and larger surface area than the FMBON. CMC-FMBON showed better adsorption performance for E2 than FMBON with the maximum adsorption capacity of CMC-FMBON and FMBON were 124.10 and 98.14 mg/g at 298 K, respectively. The experimental data can be well fitted by the model of pseudo-second-order and Langmuir model. The E2 removal by CMC-FMBON was obviously dependent on pH with the maximum adsorption occurring when the pH was acidic. The removal capacity of CMC-FMBON increased when enhancing ionic strength in solution. Background electrolytes promoted slightly E2 adsorption process whereas the presence of humic acid inhibited the E2 removal. π-π interactions, hydrogen bonds, and oxidation might be responsible for E2 removal. This research suggested that the CMC-FMBON has been considered to be a cost-efficient adsorbent for removing E2 from water. Full article

A new kind of hydrophobic and oil sorbent based on jute fiber was successfully prepared by the integration of silica onto a fiber surface via the sol-gel method and subsequent hydrophobic modification with octadecyltrichlorosilane (OTS). Compared with the hydrophilic raw fiber, the modified fiber had a water contact angle (CA) of 136.2°, suggesting that the material has good hydrophobicity. Furthermore, the ability of oil in the oil/water system (taking diesel for example) to absorb was revealed by the kinetics, the isotherm equation, and the thermodynamic parameters. Adsorption behavior was kinetically investigated using pseudo first-order and pseudo second-order models. The data mostly correlated with the pseudo first-order model. The equilibrium adsorption at 298 K was assessed by using the Langmuir and Freundlich isotherm models. The Freundlich model had greater consistency with the experimental data. The obtained thermodynamic parameters demonstrate that the adsorption of diesel is spontaneous, favorable, and exothermic. Full article
