“…Reversed-phase column chromatography (RPC) is an extremely versatile technique and has been applied successfully to the separation of various metals and organic compounds (1,2). The application of RPC has received considerable attention because it combines the selectivity of liquid-liquid extraction and the advantages of chromatographic operation.…”

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+ .

“…1 2 The application of reversed phase chromatography has received considerable attention because it combines the selectivity of liquid-liquid extraction and the advantages of chromatographic operation. In general the efficiency of reversed phase chromatographic separation depends on many interrelated parameters including the particle size of the support, surface area, flow characteristics and characteristics of the stationary phase.…”

The possibilities of preparing a packing for reversed phase column chromatography from Menderes' perlite were studied. Its physical and chemical characteristics were compared with other solid supports prepared from rocks, such as perlite and volcanic slags. A series of chemical treatments were applied to improve the mechanical and chemical properties of perlite. The experimental work covers the strong acid treatment, the strong base treatment and the silanization with DMCS. The raw perlite containing 70-73% SiO 2 was treated with NaOH to make soluble silicates and to increase it. Thus the surface and mechanical characters of the modified perlite were determined. The mean surface OH group density and the specific surface area were 3.2 p~mol/m z and 9.2 mZ/g, respectively. The modified perlite was silanized and hydrophized to load organic complexing agents. The TBP was fixed successfully on perlite up to 20% w/w. The packing prepared was used to study the chromatographic behavior of UO22+ Fe 3+.
