Abstract
This paper used wheat straw and palygorskite clay as raw materials, and phenolic resin as adhesive. By the technologies of powdering, mixing, solidifying, moulding and sintering, the palygorskite clay Modified woodceramics were obtained. And it made use of these porous composite materials to research the adsorption of the phenol wastewater, which explored the adsorption effect of the composite materials on phenol and found out the optimum conditions of adsorption by changing the ratio of raw materials, sintering temperature, dosage of composite materials, oscillating time and pH. The result of the palygorskite clay Modified woodceramics prepared by different dosing ration of raw materials and sintering temperatures on phenol showed that the removal effect of the composite materials (wheat straw: palygorskite clay=5:1, sintering temperature = 900 deg C) on phenol was best. Using the palygorskite clay modified woodceramics to adsorb the phenol wastewater. It turned out that when the dosage of the composite materials was 0.5 g, the Oscillating time was 60 mins, and the solution temperature was 25 deg C, the composite materials adsorption efficiency on phenol was the highest. In addition, the higher the phenol solution concentration and pH, the lower the adsorption efficiency was. What’s more, the absorbability of the composite materials on phenol corresponded with Feundlich adsorption model, and the saturated adsorption was 45.66 mg/L, which indicated that the palygorskite clay Modified woodceramics had strong adsorption effect to phenol. 30 Refs.
