Polyacrylate (PAA) adsorbents selectively bind low density lipoproteins (LDL) from human plasma and blood, whereas very low density lipoproteins (VLDL) are only minimally adsorbed. The adsorption of cholesterol-rich lipoproteins to PAA adsorbents is related to the molecular weight (mw) of the polyanion ligand. Ca(++) and Mg(++) inhibit the binding of LDL to PAA adsorbents. The chemical composit...

Introduction Adsorption of proteins at a solid-liquid interface is an important phenomenon in biology and highly relevant for the design of biocompatible materials. It is well-known that protein adsorption is one of the first events which take place when a foreign material comes into contact with a living body and is believed to be a key factor in controlling subsequent cellular adhesion. In th...

Fluoride pollution in waters has engulfed worldwide regions and an excess of fluoride intake always causes skeletal fluorosis. Herein, a novel hybrid nanomaterial ZrP-MPN was fabricated for fluoride retention by encapsulating nano-ZrP onto macroporous polystyrene materials modified with quaternary ammonium groups. The as-obtained materials exhibited favorable removal of fluoride ions from aqueo...

As an extracorporeal technique for blood purification, haemoadsorption was introduced in the early 1960s along with other physico-chemical methods. The problem of poor biocompatibility of uncoated adsorbents was resolved by coating adsorbent granules with haemocompatible membranes. Use of coated adsorbents instead of uncoated ones reduces the efficiency of haemoperfusion. As a result, for many ...

Biogenic Mn oxides exert important controls on trace metal cycling in aquatic and soil environments. A Mn-oxidizing bacterium Bacillus sp. WH4 was isolated from Fe-Mn nodules of an agrudalf in central China. The biogenic Mn oxides formed by mediation of this Mn oxidizing microorganism were identified as short-ranged and nano-sized Mn oxides. Cd adsorption isotherms, pH effect on adsorption and ...

This study investigated the effect of oxides on removal As when present in simple mixtures with granular activated carbon (GAC) particles. The performance these was compared other reported GAC-based adsorbents. A standard curve for ultraviolet adsorption vs. concentration obtained using silver diethyldithiocarbamate (SDDC) method to evaluate various samples. preliminary carried out find optimal...

Aflatoxins (AF) are a class of mycotoxins that impair poultry health and performance by causing immune suppression, liver damage, and changes in serum chemistry. The toxic effects of AF can be efficiently counteracted by some adsorbents. The aim of this study was to investigate fully characterized clay adsorbents in a feeding trial with broiler chickens to correlate in vitro and in vivo AF deto...

Abstract In the twenty-first century, water contamination with pharmaceutical residues is becoming a global phenomenon and threat. Antibiotic antibiotic resistance genes (ARGs) are recognized as new emerging pollutants because they can negatively affect aquatic ecosystems human health, thereby posing complex environmental problem. These nano-adsorbents of next generation remove these at low con...

One of the most significant advances in ion exchange resin and adsorbent technology has been the development of the macroreiicular pore structure. Various synthetic routes have been developed for preparing both ion exchange resins and polymeric adsorbents of high surface area and pore volume. Further, the synthesis has been developed to a degree such that the surface area and pore parameters ca...
