  • graphite isobutylene isoprene rubber highly porous cryogels as new sorbents for oil spills and Organic Liquids
    ACS Applied Materials & Interfaces, 2013
    Co-Authors: Yan Hu, Junchen Zou, Ting Gu, Wenbo Chai, Xiaoyan Liu, Hongbing Li
    Abstract:

    The preparation, by a freeze–thaw method, of new graphite/isobutylene-isoprene rubber (IIR) sorbents for oil and Organic liquid is described. Graphite was expected to improve the adsorption properties. The cryogels were prepared by solution crosslinking IIR rubber in the presence of graphite in benzene at various temperatures, using sulfur monochloride as the crosslinker, and characterized by SEM and contact angle measurements. The dried cryogels, with interconnected macropores were sponge-like soft materials, with excellent buoyancy and hydrophobicity. They also showed excellent sorption characteristics, with the best sample exhibiting maximum sorption capacities of 17.8 g g–1 for crude oil, 21.6 g g–1 for diesel oil, and 23.4 g g–1 for lubricating oil, respectively. The samples also showed excellent sorption capability for Organic Liquids, absorbing up to around twenty times their own mass. After rapid and effective desorption, taking just 3–5 h, the cryogels were recovered. They could also be reused mo...

They also showed excellent sorption characteristics, with the best sample exhibiting maximum sorption capacities of 17.8 g g(-1) for crude oil, 21.6 g g(-1) for diesel oil, and 23.4 g g(-1) for lubricating oil, respectively. The samples also showed excellent sorption capability for Organic Liquids, absorbing up to around twenty times their own mass. After rapid and effective desorption, taking just 3-5 h, the cryogels were recovered. They could also be reused more than 30 times by simply centrifuging to remove the sorbed liquid. These characteristics mean that the cryogels prepared in this study are promising materials for removal of large-scale oil or toxic Organic spills.

  • Swelling of wood. Part III. Effect of temperature and extractives on rate and maximum swelling
    Holzforschung, 1995
    Co-Authors: George I. Mantanis, Raymond A. Young, Roger M Rowell
    Abstract:

    Summary Wood swelling Rate of wood swelling The swelling of wood in Organic Liquids at elevated temperatures has been investigated with the use of Activation energy of wood a computerized linear variable displacement transformer (LVDT). Wood swelled extremely fast at high swelling temperatures. The rate of wood swelling in Organic Liquids showed a strong dependence on temperature Arrhenius equation which closely obeyed the classical Arrhenius equation. This strict linear dependence of wood swelling

  • Swelling of compressed cellulose fiber webs in Organic Liquids
    Cellulose, 1995
    Co-Authors: George I. Mantanis, R. A. Young, Roger M Rowell
    Abstract:

    Maximum liquid-holding capacities of various compressed fibers in water and in a series of various Organic Liquids have been investigated. The maximum liquid-holding capacity versus bulk density relationships gave polynomial curves, generally with a peak. Good relative correlations for cellulose, compressed fiber pellets and wood were found for the series of Liquids tested. In general, Liquids that swelled wood to a low to medium range (up to 6%) did not swell appreciably α - cellulose and sulfite pulp, while good to excellent wood-swelling agents swelled all the fibers very significantly. It was also found that the hydrogen-bonding parameter of the swelling liquid was the most important factor. The swelling rate of various compressed fiber systems in Organic Liquids was dramatically increased by raising the temperature. Activation energies and molar volume of the swelling liquid were linearly correlated .

  • Swelling of wood. Part II. Swelling in Organic Liquids
    Holzforschung, 1994
    Co-Authors: George I. Mantanis, Raymond A. Young, Roger M Rowell
    Abstract:

    The rate and maximum swelling of several North American wood species in 40 Organic Liquids have been obtained with a computer interfaced linear variable displacement transformer. Since wood swells very fast in some Organic Liquids, even at room temperature, this apparatus made it possible to obtain accurate rate data on the swelling of wood in Organic Liquids. It was found that many similarities existed between wood and cellulose maximum swelling within various solvent chemical classes. Hence, it appears that cellulose is the primary wood polymer responsible for the major amount of swelling of wood (...)
