一直以来,腐植酸的提取、制取技术备受腐植酸研究者的关注。腐植酸原料来源多种多样,使得提取、纯化方法各不相同。即便是同一种原料、相同的提取条件,应用不同的提取剂和提取工艺,也会对腐植酸的提取能力产生较大影响。为了让广大读者更全面地了解腐植酸提取、制取工艺和技术的研究进展,在纪念本刊创刊30周年之际,本栏目以“中国知网”数据库为依据,以标题和摘要中含有“腐植酸(腐殖酸、黄腐酸、棕腐酸、黑腐酸、胡敏酸、胡敏素、富里酸、腐殖质)+提取/制取”等为关键词,检索了近30年(1979-2008年)发表在《腐植酸》杂志,以及近10年(1999-2008年)发表在非《腐植酸》杂志上的该类文献,共112篇。其中,《腐植酸》杂志发表36篇;非《腐植酸》杂志发表76篇。本栏目将1979-2008年《腐植酸》杂志发表的该类文献,以标题、作者、发表年份及所在期数4要素编辑刊出;将1999-2008年非《腐植酸》杂志发表的该类文献,以标题、第一作者、发表刊物、发表年份及所在期数5要素编辑刊出。
All along, the humic acid extraction, preparation technology has attracted the attention of humic acid researchers. Humic acid sources a variety of sources, making extraction, purification methods vary. Even with the same raw materials, the same extraction conditions, the use of different extractants and extraction process, but also on the humic acid extraction ability have a greater impact. In order to let readers know more about the research progress of humic acid extraction and preparation process and technology, in commemoration of the 30th anniversary of the publication, this column is based on the database of “CNKI”, with title and abstract Containing “humic acid (humic acid, fulvic acid, fulvic acid, melamic acid, humic acid, humin, fulvic acid, humus) + extraction / Preparation ” and other keywords, retrieved nearly 30 years (1979-2008) published in “Humic Acid” magazine, and in the past 10 years (1999-2008) published in non-“humic acid” magazine of this kind of literature, a total of 112 articles. Among them, “humic acid” magazine published 36 articles; non “humic acid” magazine published 76 articles. This column will be published in the Humic Acid Magazine 1979-2008 this literature, with the title, author, year of publication and the period of 4 elements edited and published; the 1999-2008 “humic acid” magazine published in this category Literature, with the title, the first author, publication, publication year and the period of 5 elements editor.
