Important challenges in the global water situation, mainly resulting from worldwide population growth and climate change, require novel innovative water technologies in order to ensure a supply of drinking water and reduce global water pollution. Against this background, the adaptation of highly advanced nanotechnology to traditional process engineering offers new opportunities in technological...

Researchers are in continuous search of better strategies to minimize, if not prevent, the anthropogenic release toxic heavy metals, such as Cu(II) and Pb(II), into drinking water resources natural environment. Herein, we report for first time low-temperature combustion synthesis magnetic chitosan-manganese ferrite absence cross-linking agents its removal Pb(II) from single-component metal solu...

Nanoparticles of titanium diboride (TiB2) coated with a conductive polymer and subjected to an oxidizing agent was carried out in this research. TiB2 nanoparticles polypyrrole (PPy) were studied using XRD TEM techniques. Nitrogen adsorption desorption properties are covered modified understand better the surface zone, structural features, pore geometries nanoparticles. The water-based hazardous...

One of the most important directions for environmental remediation is effective removal dyes and toxic heavy metals from water using newly fabricated nanoadsorbents. Here, magnetic Fe3O4 nanoparticles were combined with nitrogen-containing functional group polymers chitosan (CS) polypyrrole (ppy) to synthesize a nanocomposite (polypyrrole@magnetic chitosan) useful removing methyl orange (MO) he...

Spherical silica particles with bifunctional (≡Si(CH2)3NH2/≡SiCH3, ≡Si(CH2)3NH2/≡Si(CH2)2(CF2)5CF3) surface layers were produced by a one-step approach using a modified Stöber method in three-component alkoxysilane systems, resulting in greatly increased contents of functional components. The content of functional groups and thermal stability of the surface layers were analyzed by diffuse refle...

<p><span>The quality of human life is compromised due to the increased concentration toxic heavy metals in air, water, and soil which directly interacted with living life. Exceed levels Cr, Cd, Cu, As, Zn, Pb, Hg influence chain not only causes damage but also greatly effects animals, plants, microorganisms. The consistent increase drawbacks traditional methods makes them a poor cho...

Sol-gel technology is a versatile tool for preparation of complex silica-based materials with targeting functions for use as adsorbents in water purification. Most efficient removal of organic pollutants is achieved by using enzymatic reagents grafted on nano-carriers. However, enzymes are easily deactivated in the presence of heavy metal cations. In this work, we avoided inactivation of immobi...
