Effects of the kinematic viscosity and surface tension on the bubble take-off period in a catalase–hydrogen peroxide system
چکیده انگلیسی

The effect of kinematic viscosity and surface tension of the solution was investigated by adding calatase, glucose oxidase, or glucose on the bubble movement in a catalase–hydrogen peroxide system. The kinematic viscosity was measured using a Cannon–Fenske kinematic viscometer. The surface tension of the solution was measured by the Wilhelmy method using a self-made apparatus. The effects of the hole diameter/cell wall thickness, catalase concentration, glucose concentration, and glucose oxidase concentration on the kinematic viscosity, surface tension, and bubble take-off period were investigated. With our system, the effects of the changes in the solution materiality on the bubble take-off period were proven to be very small in comparison to the change in the oxygen-producing rate.
