The corresponding author hereby submit a retraction email of the above articles. The corresponding author failed to inform Professor CT Chang that his graduate students, C. Y. Lin and V.S.K. Adi, were listed as the co-authors and the NSC project number was quoted in the acknowledgement without his permission. An almost identical paper had been published on-line in Chemical Engineering Journal and withdrawn by the same corresponding author and there were also some mistakes in KJChE manuscript. The corresponding author deeply regrets the uncareful publication.
