摘要：
The dependences of the fluorescence quantum yields of pyrene-1,3,6-trisulfonate and pyrene-3,5,8,10-tetrasulfonate adsorbed onto TiO2 colloid on the solution composition were investigated. The increases in pH and chloride concentration cause a decrease in the rate constants of fluorescence quenching. The results are discussed in terms of the potential of the surface of the colloid particles.
