摘要
The present invention relates to a sulfurized dye adsorbent containing methyl esterified ephippium, a production method thereof, and a method for adsorbing sulfurized dye using the same. According to the present invention, the sulfurized dye adsorbent is methyl esterified by the following steps: separating ephippium from eggshell; grinding the separated ephippium; and mixing the ground ephippium along with an acidic solution containing low alcohol, thereby exhibiting excellent sulfurized dye adsorption rate in all pH range. In addition, the sulfurized dye adsorbent is eco-friendly by containing ephippium which is protein.
