[The influence of several anions on sonoluminescence]
Abstract:
1.1 MHz ultrasound was used to induce sonoluminescence in air-saturated solutions dissolved five kinds of anions in different ranges: NO3-: 0.2-20 mg x L(-1), F- : 4-20 mg x L(-1), Cl- : 5-25 mg x L(-1), HCO3- : 8-30 mgx L(-1), SO4(2-) : 0.4-40 mg x L(-1). It was found that four kinds of the anions, Cl- , NO-, HCO3- and SO4(2-) at the above mentioned concentrations have no influence on sonoluminescence. However, only F- in the range of 4-20 mg x L(-1) can quench the sonoluminescence. The quenching mechanism was analyzed.
