Kim, Sun-Deuk ; Shin, Yun-Yeol ; Kim, Chang-Su ;
Analytical Science and Technology, volume 12, issue 6, 1999, Pages 465~471
Chloromethylated polystyrene resins supported diethylenetriamine of linear and claw types have been prepared by the reaction of diethylenetriamine with chloromethylated polystyrene. The kinetics of adsorption of transition metal ions on polystyrene resins were measured by the limited-bath technique. This paper reports the results of the diffusion coefficients, entropies of activation, and free energies of activation. The ratedetermining step of the adsorption of transition metals on the resins is a process of diffusion through the particles.

Analytical Science and Technology, volume 12, issue 6, 1999, Pages 478~483
Coagulation efficiencies of some organic compounds by aluminum based coagulants including alum, PAC, PACS were studied. The coagulation efficiency was highest at the neutral pH. It was decreased with an order of PACS, PAC, and alum at the neutral pH. The organic compounds of high molecular weights showed good coagulation efficiencies with all coagulants, while the small molecules were not coagulated. Organic compounds having more than two adjacent functional groups of OH and COOH showed coagulation efficiencies of 10~80%.

We have studied structural charecterization, electrical charge and discharge, and impedence properties for polyacene anode material derived from phenolic resin of novolak type. From the X-ray diffraction results, diffraction patterns for compounds of the three kinds of P-700, P-850, P-1000 were observed for semiirregular structural transition. A electrical charge and discharge data showed that the properties of p-850 was much better than any other samples. From the impedence properties for finding the effect of ions and electron transfer of battery, P-1000 and P-850 of high frequency of real number showed good electrical impedence properties.

Jung, Mie-Won ;
Analytical Science and Technology, volume 12, issue 6, 1999, Pages 509~514
The systematic modification of titanium(IV) isopropoxide with acetic acid as a organic additive was done and identifided by FT-IR,
NMR and UV-Vis spectroscopy. The structure was cbanged after hydrolysis-condensation reaction and drying process. The hydrolysis-condensation rates of modified Ti alkoxide with acetic acid were investigated by
NMR spectroscopy. This modified Ti(IV) alkoxide was less reactive toward hydrolysis-condensation reaction than
, which can be attributed to the stable ligand structure between Ti alkoxide and ligand. The structural change on obtained from gel powders with heat treatment was also observed by FT-IR spectroscopy.

Analytical Science and Technology, volume 12, issue 6, 1999, Pages 515~520
The spectrophotometric determination of Al(III) with thorin have been investigated. The optimum condition of pH, concentration of ligand and surfactant, and stability were evaluated. The thorin ligand offers selective separation of Al(III) from sample solution containing Fe(III), Ni(II), Cu(II), Pb(II) and Cu(II). Various surfactants were tested and Triton X-100 showed the best stability and the maximum absorbance in an aqueous solution of Al(III)-Thorin-Triton X-100 complex appears about 526 nm. The method was applied for the determination of Al(III) in mixed sample solution. Separation and preconcentration was performed with a short column filled with resorcinol-formaldehyde resin. Control of the pH during the column operation is essential because the adsorption capacities are very sensitive to change in pH. Their separation was carried out in 0.2 M acetic acid-sodium acetate buffer solution (pH 4.5) and 1.0 M

The capillary columns were made using RSL-300 fused silica capillary(I.D.: 0.53 mm, O.D.: 0.67 mm) and AG14 column resin(support : polystyrene-divinylbenzene, functional group : alkyl quaternary ammonium). The new conductivity cell and suppressor were also developed and made for capillary column ion chromatography. When several anions (fluoride, nitrite, nitrate, chlorate) were analyzed using these capillary columns, reproducible and good chromatograms were obtained.
