Mathematical modeling of heavy metal ions (Cd2+, Zn2+ and Pb2+) biosorption by chemically modified short hemp fibers
(Elsevier Science Sa, Lausanne, 2011)
Biosorption, an innovative and low-cost effective method for removal of heavy metal ions from wastewaters, primarily depends on the diffusion of metal ions through the porous structure of sorbent and the resistance effects ...
Modification of glassy carbon properties under low energy proton irradiation
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Glassy carbon plates were irradiated with 15 key H(+) ion-beam in the fluence range of 1 x 10(16)-3 x 10(18) ion cm(-2). The influence of ion irradiation on surface morphology and topology was examined by scanning electron ...
Sorption of zinc by novel pH-sensitive hydrogels based on chitosan, itaconic acid and methacrylic acid
(Elsevier, Amsterdam, 2011)
Novel pH-sensitive hydrogels based on chitosan, itaconic acid and methacrylic acid were applied as adsorbents for the removal of Zn2+ ions from aqueous solution. In batch tests, the influence of solution pH, contact time, ...
Monomer elution from nanohybrid and ormocer-based composites cured with different light sources
(Elsevier Sci Ltd, Oxford, 2011)
Objectives. To study monomer elution from four resin-based composites (RBCs) cured with different light sources. Methods. Twenty-eight premolars were randomly allocated to four groups. Standardized cavities were prepared ...
Removal of Cu2+ ions using hydrogels of chitosan, itaconic and methacrylic acid: FTIR, SEM/EDX, AFM, kinetic and equilibrium study
(Elsevier Science Bv, Amsterdam, 2011)
A removal of Cu2+ ions from aqueous solutions onto hydrogels of chitosan. itaconic and methacrylic acid has been investigated using batch adsorption technique. The extent of adsorption was investigated as a function of pH, ...
Could natural Serbian clinoptilolite efficiently remove metal ions from aqueous solutions and also be converted into a novel material after being metal-loaded?
(Editorial Universitat Politècnica de València, 2011)
Molecular Sieves: Aluminophosphates
(John Wiley and Sons Inc, 2011)
Aluminophosphate molecular sieves exhibit structural and compositional diversity. Their frameworks can be modified by other elements, thus providing novel silicoaluminophosphate (SAPO), metaloaluminophosphate (MAPO), and ...
Decolorization of reactive textile dyes using water falling film dielectric barrier discharge
(Elsevier, Amsterdam, 2011)
Decolorization of reactive textile dyes Reactive Black 5, Reactive Blue 52, Reactive Yellow 125 and Reactive Green 15 was studied using advanced oxidation processes (AOPs) in a non-thermal plasma reactor, based on coaxial ...
Efficiency and Biocompatibility of Antimicrobial Textile Material of Broad Spectrum Activity
(Wiley, Hoboken, 2011)
the antimicrobial textile material. The material is in the form of plaster wound dressing which is consisting of a nonwoven textile base containing polypropylene (PP)/viscose, a polymer carrier, and an antimicrobial active ...
Dissolution Behavior of Different Celluloses
(Amer Chemical Soc, Washington, 2011)
Celluloses from different origins were dissolved stepwise in N,N-dimethylacetamide/lithium chloride (9% v/w; DMAc/LiCl) with the aim to study the time course of the dissolution process, Completeness of dissolution in the ...
