  • Modified Sorptive Lignocellulosic Fibre Material, Preparation and Use Thereof and Method for Decontamination of Fluid and Aqueous Media
    Publication number: 20080017581
    Abstract: A modified sorptive lignocellulosic fibre material with hydroxyl groups on the lignocellulosic fibres doubly modified by esterification with a combination of monocarboxylic and dicarboxylic acid ester groups. A process for the preparation of the sorptive material. The sorptive fibre material is effective for the removal of oils and other contaminants including heavy metals from a fluid such as contaminated water by a combined sorption of hydrophobic contaminants and ion exchange.
