A Novel Binary Particle Fractionation Technique

An interesting development towards a robust particle fractionator is presented. Typically acoustic fractionators rely on time of flight in a constant acoustic field to separate different populations[1,2]. Such a system requires all particles to be concentrated to an initial known point before entering the acoustic field. As the particle population enters the acoustic field, the particles will m...

Relative Lability of Trace Metals Complexed in Aquatic Humic Substances Using Ion-Exchanger Cellulose-Hyphan

Neste estudo as frações metálicas, complexadas por substâncias húmicas aquáticas (SH) foram caracterizadas como lábeis/inertes em função do pH, tempo de complexação e concentração de SH. As SH foram extraídas por ultrafiltração e complexadas com íons metálicos bivalentes. Essas frações foram caracterizadas por processo de troca iônica utilizando resina celulósica Hyphan e procedimento em batela...

Immunoglobulin A Preparation from Human Pooled Plasma Using Plasma Fractionation and Ion Exchange Chromatography

Background: In this study we have prepared the IgA solution from normal human plasma using plasma fractionation and ion exchange chromatography. Materials and Methods: Using fractionation of plasma with cold ethanol (starting with 8% ethanol), fraction III was prepared as a suitable source for IgA preparation. Then it was treated with caprylic acid for separation of impurities. For enrichm...

Adsorption Removal of Humic Acid from Water Using a Modified Algerian Bentonite

In this study, the main objective is the preparation and the characterization of a modified Algerian bentonite based adsorbent by intercalation with hexadecyltrimethylammonium bromide (HDTMA). Natural and modified bentonites were characterized using thermogravimetric analysis (TGA), X-ray diffraction (XRD) and infrared spectroscopy (FTIR). The X-ray results indicate that the geometry of the int...
