N2 - A new experimental technique, which is based on a kinetic model for particle transport, has been proposed for determination of capture efficiency of particles by bubble flotation. A cold model experiment by using an aqueous solution and plastic particles is carried out to validate the new experimental technique. Plastic particles having poor wettability tend to adhere to bubbles and they are removed from an aqueous solution by bubble flotation. On the other hand, plastic particles good in wettability are not captured by bubbles. Capture efficiency can be estimated from a difference of transfer rate between the particles having poor and good wettability. Capture efficiency is found to be proportional to size ratio of particle and bubble, dp/db, and agrees with the theoretical results of Sutherland (1948) for a potential flow condition.
