| Abstract: | Extraction of humic acid from humic soil in Xecanwei, Yunnan, and its characteristics and adsorption capability have been studied. Experimental result showed that the extracted humic acid has higher adsorption capability to Cr-, and diluted alkali method for preparation of humic acid showed more effective. The adsorption isotherm is conformed to Langmuir equation. It is a potential adsorbent in wastewater treatment. |
