摘　　要：合成、表征了4种金属十六氯酞菁MPcCl16(M=FeⅡ,CoⅡ,CuⅡ,ZnⅡ)配合物,研究了它们对水中罗丹明B紫外光光降解的催化作用,侧重探讨了催化剂的用量和气氛等条件.发现该4种配合物的催化活性因中心金属离子不同而异,其中,FePcCl16最优,如在pH 6.86的条件下光照100 min后其催化效率可达89.86%;FePcCl16用量以0.4 g/L为佳;动态氧气和静态空气气氛有利于提高光催化降解效率.Four complex of perchlorinated metallo-phthalocyanines MPcCl16 （M=Fe^Ⅱ ,Co^Ⅱ,Cu^Ⅱ ,Zn^Ⅱ ） were synthesized and employed for the photocatalytic degradation of Rhodamine B in aqueous. The results show that their photocatalytic activity is different with the central metal of phthalocyanines and the pH value. Under the optimal pH value FePcCl16 exhibits the most photocatalytic activity. When at the condition of pH 6.86 and 100 min illumination, its photocatalytic efficiency is up to 89.86%. When the sample of FePcCl16 employed to degrade Rhodamine B, the best technical conditions are as follows, the amount of the catalyst is 0. 4 g/L and bubbling with air or oxygen.
