摘  要:
以实验室制备的黑碳为对象,对重铬酸钾氧化法测定黑碳的主要测定条件进行了比较研究。结果表明:重铬酸钾氧化法用于生物体来源的黑碳测定条件为重铬酸钾溶液浓度0.5mol/L、重铬酸钾溶液与浓硫酸的体积比1∶1,氧化时间5h。

摘  要:
The main conditions of dichromate potassium oxidation method with black carbon synthesised in laboratory were studied.The results indicated that 0.5 mol/L dichromate potassium is appropriate to black carbon derived biomass;and the optimum ratio of dichromate potassium and sulfic acid is 1∶1;the oxidation time should be controlled below 5 h.
