Effect Of Surface

Cellulose fibers were chemically modified on surface by acrylamide polymerization and glutaraldehyde crosslinking. The chemical and morphological structures of modified cellulose fibers were investigated with X-ray diffraction, FTIR spectra, and scanning electron microscopy (SEM). The crystalline conformations of the cellulose fibers were slightly changed in polymerization and crosslinking process. The wet strength of modified cellulose fibers was improved. Appreciable difference between the surfaces of native and modified cellulose fibers was observed from SEM images.

BTX stands for Benzene, Toluene, and Xylenes, which are volatile organic compounds contained in petroleum products such as gasoline. They have negative health effects and are sadly known for soil, air, and water contamination. This paper provides an investigation on BTX removal from open water systems like those represented by natural water bodies. In such systems, the evaporation process takes place, stealing the pollutants from the aqueous matrix by transferring them into the air, resulting in a secondary pollution. To prevent this situation, adsorption of these organic compounds on cellulose fibers, extracted from Spanish Broom vegetable, was studied. Raw and surface modified cellulose fibers were used for this purpose. The second ones were hydrophobized by two different green and low-cost functionalization systems (no solvent urethane functionalization and low pressure plasma treatments). Batch experiments were performed in an open system where BTX underwent two competing removing mechanisms: volatilization, and adsorption/desorption on/from the fibers dispersed in the water system. A mathematical model was implemented for the interpretation of the observed time-varying pollutant concentrations and the estimation of the kinetic constants for adsorption, desorption, and evaporation. The developed model, provided with the aforementioned parameters calibrated for each type of fibers, was then used for the prediction of their adsorption capacities both into open and closed systems.

Reactive dyes have been widely used in the dyeing of bright colourful silk fabrics. The discoloration and degradation of Reactive Red K-2G in waste water were discussed in this paper. A new heterogeneous photocatalyst named loading phthalocyanine sulfonic iron fibers (FePcS-F) was prepared by phthalocyanine sulfonic Iron supported by modified cellulose fibers in acidic condition. The photocatalytic degradation of Reactive Red K-2G was characterized by discoloration rate to evaluate the effect of catalyst dosage, catalyst loading (CFePcS-F) and solution pH. The results proved that increasing catalyst dosage and CFePcS-F significantly accelerated the dye degradation. FePcS-F catalyst showed higher photocatalytic activity when the solution’s pH value is equal to or less than 6.0, compared to alkaline medium.
