Temperature programmed desorption (TPD), XRD, SEM 및 FT-IR를 이용하여 코발트 프탈로시아닌 유도체의 황과 아민화합물에 대한 흡착효율을 조사하였다. 코발트 프탈로시아닌 유도체의 암모니아에 대한 TPD 측정결과, 산도가 낮은 온도($100{\sim}150^{\circ}C$)와 높은 온도($350{\sim}400^{\circ}C$)에서 두개의 탈착피크가 나타났다. 테트라카르복실 코발트프탈로시아닌(Co-TCPC)은 코발트 프탈로시아닌(Co-PC)보다 낮은 온도(물리적 흡착)에서 탈착피크가 약했지만 높은 온도(화학적 흡착)에서 강한 탈착피크가 나타났다. Co-TCPC와 Co-PC의 비표면적은 각각 37.5와 $18.4m^2/g$이었다. Co-TCPC와 Co-PC의 기공부피는 각각 0.17과 $0.10cm^3/g$이었다. 파과곡선으로부터 흡착용량을 계산하였더니 트리에틸 아민 가스 120 ppm의 평형농도에서 Co-TCPC의 흡착용량은 24.3 mmol/g, Co-PC의 흡착용량은 0.8 mmol/g로 나타났다. Co-TCPC와 Co-PC로 디메틸 술파이드 제거효율은 디메틸 술파이드 초기농도 225 ppm에서 각각 92와 18% 제거효율을 보였다. Co-TCPC와 Co-PC로 트리메틸아민 제거효율은 트리메틸아민 초기농도 118 ppm에서 각각 100.0%와 17.0% 제거효율을 보였다.
The adsorption capability of cobalt phthalocyanine derivatives was investigated by means of X-ray diffractometor (XRD), FT-IR spectroscopy, scanning electron microscopy (SEM), and temperature programmed desorption (TPD). According to TPD results for ammonia, cobalt phthalocyanine derivatives showed two desorption peaks at low temperature ($100{\sim}150^{\circ}C$) and high temperature ($350{\sim}400^{\circ}C$) indicating that there were two kinds of acidities. Tetracarboxylic cobalt phthalocyanine (Co-TCPC) has a stronger desorption peak (chemical adsorption) at high temperature and a weaker desorption peak (physical adsorption) at low temperature than cobalt phthalocyanine (Co-PC). The specific surface areas of Co-TCPC and Co-PC were 37.5 and $18.4m^2/g$, respectively. The pore volumes of Co-TCPC and Co-PC were 0.17 and $0.10cm^3/g$, respectively. The adsorption capability of triethyl amine calculated by breakthrough curve at 120 ppm of equilibrium concentration was 24.3 mmol/g for Co-TCPC and 0.8 mmol/g for Co-PC. The removal efficiencies of dimethyl sulfide of Co-TCPC and Co-PC in batch experiment of 225 ppm of initial concentration were 92 and 18%, respectively. The removal efficiencies of trimethyl amine of Co-TCPC and Co-PC in batch experiment of 118 ppm of initial concentration were 100 and 17%, respectively.
