“…Using CBP/ 40PE prepared from CBP and polyethylene beads (40 µm) by dry impact blending as an HPLC column packing, considerable correlation was observed between the elution concentration of proteins and their pI's. Akcay and Kilinc (B24,B25) described the preparation of a chromatographic solid support based on perlite. The standardized perlite was silanized and loaded with 20% (w/w) tributyl phosphate before use as a reversed-phase column chromatography solid support for the investigation of the chromatographic behavior of UO 2 2+ and Fe 3+ .…”

Immunochemical-Based 48R Other Detectors 48R Computation 48R Data Reduction 48R System Evaluation and Validation 48R Literature Cited 48RThis review covers fundamental developments in column liquid chromatography (LC) equipment and instrumentation for the period of October 1997 through October 1999. As with past issues, separate reviews on theory and methodology, size exclusion chromatography (SEC), and capillary electrophoresis (CE) are included in this volume of Fundamental Reviews. Capillary electrochromatography (CEC) is reviewed as part of the CE section. Because of the close relationship between capillary LC and electrophoretic techniques, references with technology pertinent to both were included. In addition, high-performance liquid chromatography (HPLC) and LC are considered synonymous. Although this review was not intended to cover applications, applications that contained developments and improvements of LC equipment and instrumentation or were used to demonstrate equipment performance were also included.The database for the majority of this review was Chemical Abstracts. This paper was not intended to be a comprehensive review of all published papers during this time period, but of those papers that were considered to be significant developments or improvements. This review has also largely restricted the covered material to the English language literature. Although the vast majority of articles were from peer-reviewed publications, included are relevant articles from widely read periodicals such as LC-GC and American Laboratory. INSTRUMENTATIONReviews. Fundamental developments in column LC equipment and instrumentation for the period of October 1995 through October 1997 were reviewed by LaCourse and Dasenbrock (A1). This paper is a continuation of that effort. Kennedy et al. (A2) reviewed fast analytical-scale separations by CE and LC. Raulin et al. (A3) discussed the use of chromatographic instrumentation in space exploration for exobiological studies. A wide range of techniques were reviewed. They noted that there is now a strong need for new chromatographic instrumentation (e.g., HPLC) in space, in particular to perform detailed molecular analyses of complex nonvolatile organics, including macromolecular compounds. Serwe et al. (A4) limited their review of HPLC to protein and peptide analysis. In addition to theory, practical aspects such

“…In their natural form, these materials are soft and have a tendency to agglomerate or form gels. [25,26] The characterization of chitosan-coated perlite beads and evaluation of their adsorption capacity for Cr(VI) are reported in this article. It is necessary to provide physical support and increase the accessibility of the metal binding sites for process applications.…”

Chitosan-coated perlite beads were prepared by drop-wise addition of a liquid slurry containing chitosan and perlite to an alkaline bath. The beads were characterized by SEM and EDS x-ray microanalysis. The chitosan content of the beads was 23%, as determined by a pyrolysis method. Adsorption of hexavalent chromium from aqueous solutions on chitosan-coated perlite beads was studied under both equilibrium and dynamic conditions. The effect of pH on adsorption was also investigated. The data were fitted to the Langmuir adsorption isotherm.The adsorption capacity of chitosan-coated perlite was found to be 104 mg/g of adsorbent from a solution containing 5000 ppm of Cr(VI). On the basis of chitosan, the capacity was 452 mg/g of chitosan. The capacity was considerably higher than that of chitosan in its natural and modified forms, which was in the range of 11.3 to 78 mg/g of chitosan. The beads loaded with chromium were regenerated with sodium hydroxide solution of different concentrations. A limited number of adsorption-desorption cycles indicated that the chitosan-coated beads could be regenerated and reused to remove Cr(VI) from waste streams.
