Abstract
PURPOSE: In preparing compound membrane by precipitation reaction of metal ion such as Cd2+ and precipitant such as thiourea, reaction solution in which the reaction is proceeding is subjected to the action of intermittent ultrasonic vibtation, thereby to provide a good quanlity, thick precipitated membrane is one operation.
CONSTITUTION: A reaction container 2 contains a mixture 6 of aqeous CdCl2 solution, buffer solution, and thiourea' and glass substrates3 placed on the holder 4. The holder 4 is rotated, and the container 2 is immersed into the thermostat bath 1 maintained at 120°C to start precipitation reaction. During the course of the precipitation reaction, intermittent ultrasonic vibration is actuated through the vibrator 5 placed in the solution 6. The vibration prevents the deposition of precipitated particulates, thus restricting precipitating membrane formation only to the substrate surface causing good quality membrane.
