“…The experimental results were compared with packings used by other authors, and it was concluded that the TBP-loaded perlite column shows approximately the same selectivity and rapidity (16)(17)(18)(19)(20)(21).…”

The S1O2 content of the mineral perlite, which is the 70-75% range, was converted to soluble silicates with NaOH. The acidification of soluble silicates in the perlite formed hydrogels which turned into xerogels upon drying. Several parameters, particle size, specific surface area, pore size and volume, and surface hydroxyl group density were investigated for perlite standardized by NaOH. The standardized perlite was silanized and loaded with 20% (w/w) tributyl phosphate before use as a reversedphase column chromatograghy solid support for the investigation of the chromatographic behavior of UO| + and Fe 3+ .

“…In the evaluation of the results we have used the socalled uniformity criterion A derived by Vigdergauz [7,8] which relates the number of peaks present (np), the base width of the sharpest peak (Wb*) and the resolution of the peak pair with the poorest resolution (R*) to the total analysis time (te*):…”

“…Helium was used as the carrier gas, at flow rates between 50 and 100 mL rain -1. The active agent of the investigated surface-layer sorbents was always NaX-type zeolite; the following solid supports were mainly used: Chromosorb W, Chromaton AW-DMCS and a special support prepared from a volcanic slag of Georgian origin calcinated at 1000 ~ [8,10]. Two hydrocarbon mixtures were used as test probes, consisting of the following compounds: Test mixture No.…”

SummaryRetention ability of different types of solid supports with respect to active agents was studied using NaXtype zeolites as the example. The relative contribution of the zeolite (active agent) and the solid support to the overall adsorption of certain hydrocarbons was determined. The role of dispersity (particle size) and depth of penetration of the active agent in the pores of the solid support was investigated, using the uniformity criterion A of Vigdergauz. The performance of chromatographic columns packed by surface-layer sorbents is compared with columns packed with the pure active agent.

SummaryA sample of a new kieselguhr is characterized and treated in order to use it as gas chromatography column support. This sample has been characterized by various analytical methods such as X-ray diffraction, scanning electron microscopy (SEM), atomic absorption and emission spectrometries and mercury porosimetry. Tests of separation of various hydrocarbon mixtures and alcohol mixtures have been achieved. Results show that the prepared supports have similar performances than those of commercial products.
