Determination of Spherosomes from Lees Materials

Abstract

To evaluate the effectiveness in adsorbing organochlorine compounds such as chloroform, dichloromethane, or benzene by lees materials, the determination of spherosomes from different lees materials was established by using a hemacytometer under an optical microscope. Rice bran, wheat bran, rapeseed, linseed, okara, and sakekasu were used for this investigation, and activated carbon was also used as a standard adsorbent material. The number of spherosomes varied from 1.82 x 10(10) particles/g for sakekasu to 4.95 x 10(10) particles/g for wheat bran. There was a high correlation between the removal efficiency in adsorbing organochlorine compounds such as chloroform, dichloromethane, or benzene by lees materials and the number of spherosomes from different lees materials.

Use of Tea or Coffee Lees as Adsorbent for Removal of Benzene from Wastewater

“…We previously reported that the number of spherosomes in lees materials increased with the removal efficiency of organochlorine compounds and benzene by these materials. 15) We regarded the special membranes as related to the uptake of chemical compounds into spherosomes. The chemical nature of the spherosomes is uncertain.…”
