Abstract
The adsorption of SSF-126, (E)-2-methoxyimino-N-methyl-2-(2-phenoxyphenyl)acetamide, on the mineral clay was exothermic. However, that on the activated carbon was endothermic, which is different from the general characteristics of physical adsorption. The release of SSF-126 from the granules highly depended on the adsorption and desorption properties of the adsorbents for SSF-126. It was possible to control the release rates of SSF-126 from the granules intentionally to a considerable degree by changing the compounding amount and quality of the activated carbon. Moreover, it is suggested that the release can be further inhibited, and also different release patterns can be obtained when combined with ethylcellulose having a controlled release function.
