胡敏酸是土壤有机质的重要组成部分,是研究土壤有机质物理化学性质的重要环节之一。本文综述了国内外在土壤胡敏酸研究中所采用的各种分析方法,详细论述了滴定分析方法在土壤胡敏酸官能团测定、土壤胡敏酸带电性质测定以及胡敏酸与金属相互作用研究中的应用,并使用滴定分析法测定了贵州喀斯特地区石灰土胡敏酸中酸性官能团及其与Ca~(2+)形成络合物的稳定系数。通过总结对比滴定分析法在研究胡敏酸方面的应用,本文认为现代滴定分析法在表征土壤胡敏酸物化特性和研究土壤胡敏酸演化规律等方面具有广泛应用前景。 |

Humic acid is an important component of soil organic matter and is a key substance in understanding the physical-chemical property of soil organic matter. This paper reviewed the development of titrimetric methods for characterization analysis of soil humic acid, especially, in identification of functional groups of soil humic acid and in measurement of electric properties of soil humic acid, and discussed the application of titrimetric analysis methods in studying interactions of humic acids and metals in soils. We employed titrimetric analyses as an example to quantify acidic function group contents in humic acids from a limestone soil sample and evaluated the complex stability of Ca~(2+) and different humic acid fractions. By summarizing the new progress in titration analysis method and comparing titration method with others, this paper concluded that the titration analysis method is an important approach and has broad applications in studying the physicochemical property and the evolution rule of soil humic acid. |
