New Adsorbents for Purification: Selective Removal of Aromatics

Adsorption of benzene and cyclohexane on ®arious Y-zeolites was in®estigated to de®elop sorbents for the purification of aliphatics by remo®al of aromatics. Ag-Y showed superior benzenercyclohexane selecti®ities to Na-Y, Pd-Y, and H-USY. Separation factors greater than 10 5 were obtained with Ag-Y at low concentrations of benzene. High selecti®ities were achie®ed by the strong interaction betwe...

Adsorbents for TLC Adsorbents for coating TLC plates

302 This chapter gives a detailed description of the adsorbents manufactured by MACHEREY-NAGEL for coating of TLC plates. Especially for quantitative investigations, however, we recommend our ready-to-use layers with these adsorbents, since production of high-quality homogeneous layers for reproducible separations requires intense practical experience in coating techniques, which today is not a...

Assessing Innovative Arsenic Adsorbents

According to a 1999 study by the National Academy of Sciences, arsenic in drinking water can cause several types of cancer, harm the central and peripheral nervous systems, cause serious skin problems, cause birth defects and reproductive problems. The USEPA published a Final Arsenic Rule in the Federal Register that established a revised Maximum Contaminant Level (MCL) for Arsenic of 10μg/L (U...

New Nano-Adsorbents for the Removal of Chromium (III) and Mercury (II) from Aqueous Solutions

Polyvinyl alcohol/ glycerin- magnetic iron oxide nanoparticles (PVAGLPs) have been synthesized successfully by hydrothermal method. The as-prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectra (FTIR). The adsorbed activities of the polyvinyl alcohol/ glycerin- magnetic iron oxide nano particles (PVAGLPs) were ca...
