摘要：
The fluorescences quenching phenomena of 9, 10-diphenylanthracene (DPA) by tryptophan in sodium dodecylsulphate (SDS), cetyltrimethylammonium bromide (CTAB) and triton X-100 micelles have been studied at pH = 7. The dynamics of tryptophan association to the micellar pseudophase and the effect of micellar charge upon intramicellar bimolecular quenching constants have been investigated.
