摘　　要：以腐殖酸与亚硫酸钠反应生成的磺化腐殖酸钠为主要原料,与交联剂脲醛树脂胶反应,制备了脲醛-磺化腐殖酸吸附树脂。研究了该树脂对Cr(Ⅵ)的吸附性能。结果表明,脲醛-磺化腐殖酸吸附树脂对Cr(Ⅵ)有较好的吸附性能,并随着吸附时间和Cr(Ⅵ)初始浓度的增大而增大。该树脂红外光谱分析表明,磺化腐殖酸钠与脲醛树脂有很好的交联效果。The urea formaldehyde-sulfonated humic acid resin was prepared with urea-formaldehyde resin adhesive and sulfonated humic acid sodium as the starting materials. The adsorption property of this resin for Cr（ Ⅵ ） was studied. The results revealed that urea formaldehyde-sulfonated humic acid resin had an excellent adsorption property for Cr（ Ⅵ ）, which is enhanced with the increase of adsorption time and the initial concentration of Cr（ Ⅵ）. The FTIR showed that urea-formaldehyde resin can be easily crosslinked with sulfonated humic acid sodium.
