研究将土壤有机质测定方法(KMnO4和K2Cr2O7氧化法)运用到生物质炭上,探讨了生物质炭(Biochar,BC)降解过程中易氧化部分的定量方法.研究结果显示,生物质炭抗氧化性存在不均一性,既可能是生物质炭制备过程产生的热解小分子物质,也可能是生物质炭降解产生的易氧化部分;进一步选定重铬酸钾作为氧化剂,确定氧化条件,氧化降解前后生物质炭,得出生物质炭降解确实产生易氧化部分.本文研究建立的生物质炭易氧化部分定量法可以作为生物质炭的降解程度的定量指标,为土壤中有机碳循环提供重要研究方法.值得强调的是该定量法应用到不同种类的生物质炭上须对氧化条件做出相应讨论.

The determination of organic soil matter, in which potassium permanganate or potassium dichromate is used as oxidant, was employed to quantify the easily oxidized part of biochar during its degradation. The results showed that antioxidant activity of biochar was uneven. It might be due to the generation of small molecules via pyrolysis during preparation of biochar or the easily oxidized part in the degradation of biochar. Potassium dichromate was further used to determine the oxidation condition, and oxidized biochar was incubated in different ways. The oxidation results of original biochar and degraded biochar displayed the occurrence of easily oxidized part during degradation. It was found that the degree of degradation of natural biochar was relatively high, and active organics could indicate the degradation of biochar. Thus, the oxidization with potassium dichromate could be used to quantify the easily oxidized part of biochar. It is suggested that the easily oxidized part could b
