Abstract: This paper studies the chemical absorption - to deal with smoke in the biotransformation of NO, through the constant temperature shaker experiment to study the different electronic shuttle body of Fe(III)EDTA impact of the shuttle to find the appropriate body to strengthen e-Fe(III)EDTA reduction rate . The experimental results show that: In this experiment, three selected e-shuttle body, with better representation, the selection of Lloyd's to increase although the purple Fe(III)EDTA reduction rate, but the range is not great, mainly because of The Institute's research study Fe(III)EDTA has a relatively low redox potential, thus the use of electronic shuttle to restore the body to strengthen its rate is not achieved a desirable result.
