摘要 The UVA spectra and the reaction of 5-(p-Leuphenyl)-10,15,20-triphenylporphyrin[H 2(p-Leu)TPP]adsorbed on AgCl colloid in two different solvent-anhydrous alcohol and glacial acetic acid were studied.The experimental results show that H 2(p Leu)TPP exists in equilibrum between the diacid form H 2(p Leu)TPP 2+ and the free base H 2(p Leu)TPP.At pH=9 5-11 0 the H 2(p-Leu)TPP is converted into Ag(Ⅱ)(p Leu)TPP on AgCl colloids.
