Background: The development of new emerging nanomaterials for water treatment has attracted more and more interests recently. MXenes is a generic term for a series of new twodimensional (2D) transition metal carbides and carbonitrides materials which have graphene-like structure. As a new type of 2D lamellar nanomaterial, many researches has focused on the design and synthesis of MXene-based nanomaterials owin Read More

Background: Water contamination by noxious heavy metals due to urbanization is a global environmental problem. Heavy metal ions pollution makes the water unsuitable for drinking and is also highly toxic to human beings and eco-system. The remediation of heavy metals is therefore very crucial. Methods: Adsorbents based on biopolymer and eco-friendly polymer composites have been developed and fabricated to re Read More

Background: The presence of pharmaceuticals (PACs) drugs in the environment and their detection and quantification have emerged as one of the challenging issues for the scientific community. Introduction: The gold standard, an anti-diabetic drug, Metformin has a strong potential to contaminate the aquatic bodies, being a highly polar drug. Different analytical methods based on spectroscopic evaluation or chromato Read More

Background: More and more chemical substances are being released to the environment. Therefore, environmental problems caused by different pollutants have attracted long-term attention. Objective: Sample pretreatment has always been the bottleneck restricting the development of residual drug analysis, so the latest development in various pretreatment technologies and current status for different residual drugs in Read More

Background: Water is undoubtedly a very precious resource that helps life thrive on this planet, and its pollution is a problem, which is potent in erasing almost all forms of life on the earth. Hence, considering the magnitude of this problem, studies and experiments have been focused (from the day water pollution was recognised as an eminent issue) on monitoring and finding possible solutions for water pollution. While the l Read More

Background: Diesel mainly consists of paraffin and thio-aromatic compounds. Sulfur present in diesel exhaust is the major challenge for oil refineries. Sulfur is an oxidizing element that discharges as acute pollutant in the environment, having adverse effects on human and animal life. Introduction: The scope of this review paper is to discuss and highlight the recent advancements in the process of desulfurization of dies Read More

Background: Pollution in water is of concern because of its negative influence on human health and impact on ecosystems. Three-dimensional (3D) structures in the form of inverse opals and opals-like structures were constructed on a scale of millimeters for their use in the adsorption of heavy metals adsorption on manganese oxide-covered surfaces. Objective: Manganese oxides both, as commercial powders and as synthesize Read More

Background: Heavy metal toxicity has proven to be a major threat and there are several health risks associated with it. The toxic effects of these metals, even though they do not have any biological role, remain present in some or the other form harmful for the human body and its proper functioning. They sometimes act as a pseudo-element of the body while at certain times they may even interfere with metabolic proces Read More

Background: Silicon Carbide (SiC) ceramics are promising engineering material due to its phenomenal properties, such as strong corrosion resistance, high-temperature hardness, wear resistance, high thermal conductivity and high stability in an aggressive environment. The key problem of SiC is low fracture toughness due to its brittle nature and to circumvent this, herein high ductile material like MWCNT was us Read More

Background: Supercritical fluid chromatography (SFC) is one of the powerful analytical techniques of modern times. Recently, extensive analytical work has been reported and is in progress by utilizing the advanced features of SFC. Low solvent consumption, high sensitivity, and solvent recovery make it advantageous over the traditional liquid chromatographic techniques. It utilizes supercritical fluids having properties of Read More

Background: Indole-3-acetic acid (IAA) is an important growth hormone for plants obtained by biosynthesis from tryptophan. Aim: In this paper was studied the competitive transport of two biologically active compounds, indole-3-acetic acid (IAA) and tryptophan (TRP), through a liquid membrane. Methods: The separation of the two compounds was obtained using a hybrid liquid membrane system having trioctylphosphi Read More
