电位滴定法表征炭基材料表面官能团进展研究
|
摘要
炭基材料表面官能团影响炭基材料表面酸碱性,同时影响炭基材料对重金属以及有机污染物的吸附能力。探索和建立炭基材料表面官能团的表征方法可以为深入研究炭基材料与污染物的吸附机理奠定实验方法上的基础。电位滴定法是一项有效的官能团表征手段,但目前相关文献尚未对该方法在表征炭基材料表面官能团的研究进行总结。本文从电位滴定法的方法学、电位滴定法的原理、影响电位滴定法的因素、电位滴定法的优缺点等四个方面出发,总结了电位滴定法表征炭基材料表面官能团的研究进展,以期为采集和处理电位滴定数据提供思路。
Functional groups on carbonaceous materials affect the acid-base properties, and meanwhile determine the adsorptive capability for metals as well as organic pollutants. Thorough studies of carbonaceous materials require the characterization of their functional groups. Potential titration is an effective method to characterize functional groups but has not been reviewed in the field of carbonaceous materials. The overall objective of this paper is to summarize the principles of potential titration, its methodology, and the factors influencing potential titration, as well as the advantages and disadvantages of potential titration, to provide suggestions of the data collecting and handling from potential titration.
