Ethylene Diamine Tetra Acetate - traps/scavenge Holes (h+)

Iso Propyl Alcohol (IPA) - traps/scavenge Hydroxyl radicals (OH. )

Silver Nitrate (AgNO3) - traps/scavenge Electrons (e-)

1,4-benzoquinone - traps/scavenge Holes (h+)

There are many other chemicals too, which have been employed as scavengers.

Can anyone explain the mechanism involved in each reaction?
