Study on Extracting Humic Acid from Peat by Two-step Method with Electrolytic Water

Li Liang, Wang Dehan, Xie Xilong (College of Resource and Environment, South China Agricultural University, Guangzhou, 510642)  
The method extracting humic acid with NaOH is used widely at home and abroad, while it has some short-comings. Electrolytic water not only is an especial and functional water with sterilization, deodorization, activation and oxidation, but also is economical and environmental-friendly, and easy to be produced. In this paper, multi-experiments were designed to analyze the extracting effect and rule from peat using two-step method, i.e., pretreated with acidic electrolytic water fi rstly, and then extracted with alkaline electrolytic water. Some optimal parameters were defi ned finally, such as the initial concentration of NaCl in electrolytic water was 5%, the ratios of acid-peat and alkaline-peat were 10∶1 and 15∶1, and the reaction temperature and reaction time were 40 ℃and 3 h, respectively. This paper also analyzed the practical value of this method, and would provide references for industrial application.
