Ammonium hexafluorosilicate, (NH4)2SiF6, has been found to be partially selective for removing surface acidity in zeolite ZSM-5. Under static digestion conditions using HZSM-5 extrudate, the zeolite was found to lose approximately 30% of its acid sit

X-Radiolysis of aqueous erythrosin (2′,4′,5′,7′-tetraiodofluorescein) under reducing conditions (complete removal of OH radicals) has given rise to dye-bleaching and formation of leucoerythrosin, due to reactions of erythrosin with ${\rm e}_{
