“…From literature concerning the development and application of the stationary phase for thin-layer chromatography (1)(2)(3)(4)(5), it is observed that plain silica gel is commonly used for TLC studies of inorganics. It is also noticed that compared to plain alumina, cellulose, kieselguhr, chitin, and chitosan, silica gel impregnated layers are more frequently used for the selective separation of many heavy metals (6).…”

Silica gel H impregnated with microcrystalline cellulose gel in alkaline medium was used as a stationary phase for the thin layer chromatography of heavy metal cations. A mixture of 10% aqueous potassium thiocyanate and triton X-100 in 1:1 v/v has been identified as the best combination of mobile phase for achieving selective separation of cobalt from nickel. The efficacy of the chromatographic system has been investigated by monitoring reproducibility of R F values and spot compactness with respect to the change in sample concentration and matrix effect. The improved selectivity of impregnated silica gel H was expounded by SEM and FTIR studies. The typical surface modification as well as the chemical changes in impregnated silica gel H was attributed. Chromatograms of the cations were quantitatively evaluated by scanning densitometry in comparison with ICP elemental analysis. The proposed method is applied for the determination of cobalt and nickel cations in spiked samples of geological and industrial origin.

This paper provides a bibliography of the 1995 journal literature for adsorptive and membrane-type separations. The references are taken from the 50 most important chemical engineering journals. This paper provides an update to the literature as provided in previous bibliographic papers (Ray 1990a, 1991, 1994, 1995, 1996). A bibliography of the chemical engineering journal literature from 1967–1988 has been published by the author (Ray 1990b), and can provide access to a wider range of topics. A complete bibliographic listing of the chemical engineering journal literature from 1989 to 1995 (with subsequent six-monthly updates) is available on a CD-ROM database and full details can be obtained from the author. The papers included have been divided into the following subject groups: theory; design data; adsorbents; PSA and cyclic systems, and applications; liquid-phase adsorption; ion exchange, chromatography, etc.; membranes; and membrane-type separations.
