钯/铝双金属体系对3-氯酚的脱氯降解
Dechlorination degradation of 3-chlorophenol with Pd/Al bimetallic system
摘要
Abstract
The catalytic dechlorination of 3-chlorophenol(3-CP) in aqueous solution with Pd/Al bimetallic system was investigated.The Pd/Al bimetallic particles were prepared with the cementation method.The stability of dechlorination reactivity of Pd/Al was tested.The effects of the solution pH and the amount of Pd loading at Al particles on dechlorination performance were studied.The results indicated that 3-CP(0.389 mmol/L) could be rapidly dechlorinated into phenol by Pd/Al particles with 99% conversion rate during 30 min under the conditions of pH ≤ 4.0 and 1.43% Pd loading.During the repeated tests,Pd/Al particles maintained well stability for the dechlorination of 3-CP,which is related to the spontaneously formed oxide film on Al substrate.The characterizations of Pd/Al particles indicated that the tiny Pd islets were uniformly dispersed on Al particle surface and the surface area of Al particles greatly increased due to Pd loading.As a result,the high dechlorination performance was obtained in this work.关键词
