© 2006-2016 Asian Research Publishing Network (ARPN). All rights reserved.A oil products are among the most dangerous pollution of water objects. They have a deleterious effect on the physiological and biochemical processes in the body of biological objects. In recent years, more and more attention is paid using of industrial waste for water treatment from oil products. In this study, the composite magnetic sorption material was received by chemical sedimentation using of the waste of MDF production (wood fiber) and iron chloride (II) and (III). Fractional composition and physico-chemical characteristics (Tamped density, content of moisture, ash content, buoyancy, specific surface area) of the reagent was detected, the micrographs were obtained by scanning electron microscope. The elemental composition of materials was identified using the method of energy-dispersive X-ray spectroscopy. The remanent magnetism and the coercive force of the samples of modified wood fiber were calculated According of obtained hysteresis loops. IR spectra of the sorption materials were obtained and described using the method of FTIR spectroscopy in a frequency range of 400-4000 cm-1. Oil sorption capacity and water uptake of waste wood fiber and magnetic composite sorbent were evaluated in static system. Increase of oil sorption capacity and decrease of water uptake after modification of waste wood fiber was observed. Experiments to remove oil pollution from the water surface were carried out. The effectiveness of the proposed sorption material was discussed

Sorption materials based on waste of wood fiber for collecting of oil from the water surface

The paper presents studies of the physicochemical and adsorption properties of magnetic composite materials based on wood fiber wastes produced by MDF panels and magnetite. The process of obtaining composite sorbents consisted in depositing nanoscale magnetite corpuscles on the outer and inner surfaces of wood fibers with ammoniacal water from a solution containing a mixture of bivalent and trivalent ferric chloride. To reduce the degree of water absorption, the obtained materials were subjected to cultivation with a hydrophobizing composition. The physico-chemical characteristics of the samples of the initial and modified materials were indentified. It was found that after the modification observes a significant increase in the buoyancy index associated with the use of a hydrophobic agent is observed, also an increase in ash content conditioned by the presence of magnetite in the composite. The formation in the pores and on the surface of magnetic wood fibers was confirmed by X-ray phase analysis. It was found that the influence of ultrasonic oscillations upon precipitation of magnetite increases by 18% the specific surface area in comparison with the material obtained without applying ultrasound. The influence of the thickness of the oil membrane on the oil capacity and water absorption was studied. For all the materials in question, as the thickness of the oil membrane increases, percentage of water absorbed by the sorbents together with the oil decreases. With an oil membrane thickness of 3 mm, the water absorption for the CS sample is 0.3 g/g, for the CS us sample 0.4 g/g, the oil capacity for CS 6.4 g/g, for CS us 7.1 g/g. To evaluate the sorption properties of the samples, the sorption quality index was calculated. So, the index of sorption quality compared with the oil of the carbon deposit is 0.8 for the original material and 4.6 and 5.0 for the CS and CS us samples, accordingly

Adsorption of heavy metals ions and oil products by magnetic composite sorbents based on waste of wood fiber

Copyright © 2019 American Scientific Publishers. All rights reserved. Magnetic composite sorbents (MCS) based on wood fibre waste (WFW) produced by MDF and synthetic magnetite (Fe 3 O 4 ) were obtained in the framework of the presented work. The process of obtaining MCS consisted in deposition of Fe 3 O 4 nanoparticles on the surface of WFW with ammonia water from a solution containing a mixture of trivalent and bivalent iron chlorides. Physicochemical and adsorption properties of composite materials are investigated. It is established that the effect of ultrasonic vibrations during Fe 3 O 4 deposition increases the specific surface area in comparison with the materials obtained without the imposition of ultrasound. The main components of MCS are oxygen, carbon, nitrogen and iron according to the elemental analysis. The presence of a small amount of calcium, magnesium, silicon and iron in the original fiber is explained by the use of binding components in the production, as well as the adhesion of mechanical particles. There is a noticeable increase in the mass fraction of iron associated with Fe3O4 deposition after modification. Experiments on purification of aqueous solutions using MCS have shown that the average degree of purification from ions of heavy metals and petroleum products varies from 79 to 86% depending on the content of Fe 3 O 4 in the composite. Deposition on the surface of WFW Fe 3 O 4 allowed to increase the efficiency of purification of aqueous solutions from heavy metal ions by more than 20%. It is revealed that at increase of iron content in the composition of the composite from 1 to 25% the efficiency of purification from dissolved petroleum products is reduced by 16%. It is established that MCS-1 and MCS-5 sorption materials possess the best adsorption properties. The subsequent increase in the content of Fe 3 O 4 in the composition of composites does not lead to a significant improvement in the adsorption properties, leads to an increase in ash content, worsens the strength and reduces the performance of purification systems in dynamic conditions due to the increase in the pour density of composite materials
