Both the regression equations show that ultrasonic amplitude hasa significant (p < 0.05) effect on the TMA. No significant effect(p > 0.05) of sonication time on TMA when using methanol whilethere was significant effect (p < 0.05) using ethanol. The interactionbetween amplitude and sonication time did not have a significanteffect (p > 0.05) for both equations.
