Tunable alkaline anion-exchange membranes based on QPMBV are synthesized using a bottom-up approach, miniemulsion copolymerization, which can incorporate functional groups into the copolymers with designated composition and high molecular weight. The mechanical and electrochemical properties of the obtained QPMBV membranes are tuned by varying the composition. It is found that the ion exchange ...

The serum proteins designated as y-globulins include all proteins of the slowest moving of the several major protein groups seen on serum electrophoresis conducted at alkaline pH (2). Among the y-globulins of normal serum are proteins of differing electrophoretic mobility (3,4), proteins with sedimentation coefficients of 6.6 S and 18 S in the ultracentrifuge (2, 3, 5, 6)) many individual antib...

An Adsorbent based treatment system is presented for toxic metal removal from rinsewater streams. The adsorbent is a Mg-A1 oxide anion exchange material with high capacity (approaching 5.5 meq/g) and strong selectivity for difficult to treat species such as Electroless plating metal chelates, Fixed Cyanides and chrome conversion solutions. Data is presented describing treatment of various metal...

High-resolution anion-exchange chromatography of human urine can resolve more than 150 constituents that absorb ultraviolet light. Prefractionation of urine on Sephadex G.10 helped us identify the constituents and simplified the anion-exchange chromatogram. The material associated with the 13 peaks obtained by gel chromatography was pooled and concentrated into six fractions, which were subsequ...

Unidirectional (36)Cl(-) efflux via the red blood cell anion exchanger was measured under Cl(-) self-exchange conditions (i.e. no net flow of anions) in rainbow trout Oncorhynchus mykiss and red-eared freshwater turtle Trachemys scripta to examine the effects of acute temperature changes and acclimation temperature on this process. We also evaluated the possible adaptation of anion exchange to ...

This study was designed to investigate the effect of anaerobic digestion on biochar produced from sugarcane bagasse. Sugarcane bagasse was anaerobically digested to produce methane. The digested residue and fresh bagasse was pyrolyzed separately into biochar at 600 degrees C in nitrogen environment. The digested bagasse biochar (DBC) and undigested bagasse biochar (BC) were characterized to det...

Low-cost adsorbents were tested to remove anionic surfactants from laundry rinsing water to allow re-use of water. Adsorbents were selected corresponding to the different surfactant adsorption mechanisms. Equilibrium adsorption studies of linear alkyl benzene sulfonate (LAS) show that ionic interaction results in a high maximum adsorption capacity on positively charged adsorbents of 0.6-1.7 gLA...

Nitrate is an anion of major importance particularly in biological areas. Excessive amounts in water supplies indicate pollution from sewage or agricultural effluents. The effects of excessive quantities of nitrate in water are well known. In this research structural modification of natural clinoptilolite by isomorphic substitution was performed. Isomorphously substituted zeolite was prepar...

Antioxidant activity of Berry (Morus alba var. nigra) was investigated. For superoxide anion radical assay, the superoxide anion radicals were generated by a pyrogallol auto oxidation system, Nitric oxide radical inhibition by the use of Griess Illosvoy reaction and reducing power was determined according to the Oyaizu method. At least this sample was represented a potential antioxidant capacit...
