    Flexible Pvc-Silica Composites as an Adsorptive Material for Water Soluble Dyes
    (Smithers Rapra Technology, 2013) Ulutan, Sevgi; Yetgin, Senem; Balköse, Devrim
    Methylene Blue (MB) adsorption studies were performed on flexible Polyvinyl Chloride/Silica composites which were obtained by using plastisol-plastigel technology. Change of MB concentration in aqueous phase as the adsorption process advanced was followed by using visible spectroscopy. The diffusion of MB through the composites exhibited non-Fickian behavior with a diffusivity of 10-11 m2s-1. Making use of such PVC-silica composite sheets as column packing, the packing time will be reduced and the surface available for diffusion will be increased. © 2013 Smithers Rapra Technology.

    Water Vapour Adsorption on Organic and Inorganic Polymers
    (Springer Verlag, 2003) Balköse, Devrim; Özkan, Fehime; Ulutan, Sevgi; Ülkü, Semra
    Water vapour adsorption on polymers affects their processing behaviour and useful properties. Water vapour adsorption on organic polymers, silk, Nylon 6 fibres in undrawn and permanent set forms, polyester micro fibres, plasticised PVC films with 60 phr dioctylphthalate (OOP) and inorganic polymer sepiolite particles were investigated in this study. The materials were examined using the BET equation. The surface areas of silk, cast Nylon 6 and muss Nylon 6 were determined as 108, 46 and 23 m2 g-1, respectively. Sepiolite did not fit BET equation. Polyester and PVC adsorbed very small amounts of moisture.
