Application of NaOH treated Polyporus versicolor for removal of divalent ions of Group IIB elements from synthetic wastewater
(Elsevier Sci Ltd, 2002)
Three different forms of Polyporus versicolor, i.e. alkali-pretreated, heat-inactivated and active, were used for the removal of the divalent ions of Group JIB elements from aquatic systems. The biosorption of Zn(II), ...
Procion Brown MX-5BR attached and Lewis metals ion-immobilized poly(hydroxyethyl methacrylate)/chitosan IPNs membranes: Their lysozyme adsorption equilibria and kinetics characterization
(Pergamon-Elsevier Science Ltd, 2002)
Interpenetration networks (IPNs) in membrane form were synthesized from 2-hydroxyethyl methacrylate (HEMA) and chitosan (pHEMA/chitosan) via UV-initiated photo-polymerization in the presence of an initiator alpha, ...
Membrane with incorporated hydrophobic ligand for hydrophobic interaction with proteins: application to lipase adsorption
(Wiley, 2002)
In this study, phenylalanine as a hydrophobic ligand was covalently attached on a comonomer, methacryloyl chloride. Then, poly(2-hydroxyethyl methacrylate-co-methacrylamido-phenylalanine), poly(HEMA/MAPA), membranes were ...
Separation of human-immunoglobulin-G from human plasma with L-histidine immobilized pseudo-specific bioaffinity adsorbents
(Marcel Dekker Inc, 2002)
The pseudo-biospecific affinity ligand L-histidine immobilized poly(2-hydroxyethylmethacrylate) (PHEMA) in spherical form (100-150 mum in diameter) was used for the affinity chromatographic separation of human-immunoglobulin-G ...
Cadmium and mercury uptake by immobilized Pleurotus sapidus
(Scientific Technical Research Council Turkey, 2002)
Pleurotus sapidus basidiospores immobilized onto Ca-alginate beads were used for the removal of cadmium and mercury ions from aqueous solutions. The biosorption of Cd(II) and Hg(II) ions on the alginate beads and both ...
Flavonoid patterns in Convolvulus L., (Convolvulaceae) species from Morocco
(Pakistan Botanical Soc, 2002)
This study was undertaken to document the distribution of chemical components and determine whether phytochemical characters support the delimitation of the taxa in the genus Convolvulus L., from Morocco. Twenty taxa from ...
A new species of Scorzonera L. (Asteraceae) from Anatolia, Turkey
(Pakistan Botanical Soc, 2002)
Scorzonera adilii A. Duran sp. nov., is described from the Aydos Mountain (C5: Konya) in Turkey. It is related to S. rigida Aucher, from which it mainly differs in its lanceolate leaves and features of pappus.
Selective recovery of mercury by Procion Brown MX 5BR immobilized poly(hydroxyethylmethacrylate/chitosan) composite membranes
(Elsevier Science Bv, 2002)
Metal chelating membranes have advantages as adsorbents in comparison to conventional microspheres or beads because they are not compressible and they considerably eliminate internal diffusion limitations. The aim of this ...
Heavy metal separation capacity of a porous methacrylamidophenylalanine containing membrane based on a polyhydroxyethyl methacrylate matrix
(Marcel Dekker Inc, 2001)
The abilities of various sorbent materials for heavy metal removal have been reported in the literature. We have developed a novel approach to obtain high metal-sorption capacity utilizing a membrane containing ...
Zinc ion-promoted adsorption of lysozyme to Cibacron Blue F3GA-attached microporous polyamide hollow-fiber membranes
(Elsevier Science Bv, 2001)
Dye-affinity and metal chelate affinity adsorption are increasingly used for protein separation. Synthetic hollow fiber membranes have advantages as support matrices in comparison to conventional bead supports because they ...
