查询词典 coulometry

In this thesis, shikonin, cryptotanshinone and 5-fluorouracil (5-FU) were selected as the objects for several aspect studies: In Chaper 2, the electrochemical behavior of shikonin was investigated by cyclic voltammetry, linear sweep voltammetry, chronocoulometry and bulk electrolysis with coulometry on a glassy carbon electrode. Triple strand DNA modified electrode was preparated and used to investigate the interaction of shikonin with DNA. It was found that it is hydroquinone of shikonin to embed in DNA and interacted with guanine and adenine of DNA.
