Abstract

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.
