Catalytic dechlorination of o-cllorophenol by nanoscale Pd/Fe

Abstract： Transformation of chlorophenols by nanoscale bimetallic particles represents one of the latest innovative technologies for environmental remediation. Nanoscale Pd/Fe bimetallic particles were synthesized in the laboratory for treatment of o-chlorophenol. Most of the nanoscale particles are in the size range of 20-100 nm. BET specific surface area of the nanoscale Pd/Fe particles is 12.4 m2/g. In comparison, a commercially available Fe powder( ＜100 mesh) has a specific surface area of just 0.49 m2/g. Batch experiments demonstrated that the nanoscale Pd/Fe bimetallic particles can effectively dechlorinate o-chlorophenol. Dechlorination efficiency is affected by the mass fraction of Pd in the bimetal, nanoscale Pd/Fe mass concentration and mixing intensity. 作 者： WEI Jian-jun    XU Xin-hua    WANG Da-hui   作者單位： Department of Environmental Engineering, Zhejiang University, Hangzhou 310027, China  期 刊： 環(huán)境科學(xué)學(xué)報(bào)(英文版)  ISTICSCI   Journal： JOURNAL OF ENVIRONMENTAL SCIENCES  年，卷(期)： 2004, 16(4)  分類號(hào)： X13  Keywords： nanoscale particles    Pd/Fe    dechlorination    o-chlorophenol
