Development of oil-absorbent using by curdlan = Curdlan을 이용한 기름 흡착제의 개발에 관한 연구

Abstract

Experimental studies were carried out to develop oil-absorbent using curdlan solution or gel. Curdlan sponge was prepared by freeze drying. Surface of curdlan sponge was observed with Scanning electron microscopy(SEM). Curdlan sponge absorbed more than 9 times oil and curdlan was recovered by gellation. Curdlan solution gelled at higher temperature than 50℃ and dissolved at pH 11.0 and viscosity of curdlan solution increased at 40~50℃.
