[求助] 离子液体 缓蚀

两种阴离子分别为Cl-和HSO4-的离子液体,讨论缓蚀率大小
1-Butyl-3-methylimidazolium chlorides (BMIC)
1-Butyl-3-methylimidazolium hydrogen sulfate ([BMIM]HSO4)

其中文章有这样一段解释,

Meanwhile, the presence
of the electron donating groups on the imidazolium base structure
(Cl and S), increases the electron density on the nitrogen of the
–C N– group, resulting high inhibition efficiency. In particular, S
atom is found to have excellent ability of offer free electrons [35].
Therefore, [BMIM]HSO4 is more effective than BMIC in inhibiting
the corrosion of mild steel in HCl.
请问他所说的供电基团是Cl-和HSO4-还是单纯的指Cl原子和S原子呢??
因为自己的论文也涉及到这个问题,求大神指教!!!
