该项目旨在确定陆源和微生物来源的天然有机物(NOM)的电子转移(氧化还原)特性,以及这些氧化还原特性对活性氧物种生成、金属转化和碳循环的影响。将在黑暗和光照条件下使用含有苯二酚和硫醇官能团的模型化合物以及具有良好特性的腐殖质和藻类分泌物进行实验和计算研究。将建立这些过程的动力学模型,从而能够预测NOM介导的电子转移过程对氧化剂生成、金属转化和碳循环的影响。
英文摘要
This project aims to determine the electron transfer (redox) properties of terrestrially and microbially-derived natural organic matter (NOM) and the implications of these redox characteristics to reactive oxygen species generation, metals transformation and carbon cycling. Experimental and computational studies using model compounds containing quinone and thiol-containing functional groups as well as well-characterised humic substances and algal exudates will be undertaken under both dark and light conditions. Kinetic models of these processes will be developed enabling prediction of the impact of NOM-mediated electron transfer processes on oxidant generation, metals transformation and carbon cycling.
