✦ Synopsis

Factors influencing the bubble stabilization by spherical monodisperse SiO2 particles with diameters ranging from 20 to 700 nm have been examined. Results showed that hydrophobic silica particles had good stabilization for foam produced by sodium dodecyl sulfonate in alkaline aqueous medium. The smaller the particle size, the stronger the stabilization. The possible mechanism of the stabilization effect has been discussed.
