摘要
提取海河河口水体表层底质中的富里酸(FA)和胡敏酸(HA),对其性能进行了表征。本文所用提取方法比较接近于原位提取,具有较好的重现性;海河河口闸内、闸外水体表层底质中的FA、HA状况大致相同,稍有差异;所得FA和HA均含有烷基和稳定自由基。
The fulvic acid (FA) and humic acid (HA) in Haihe estuary surface sediments were extracted. The extractive method has good reproducibility. The properties of FA or HA in the surface sediments inside and outside the sluice on Haihe estuary are roughly the same respectively. All of the FA and HA contain alkyls and stable free-radicals.
