摘要
在氨性溶液中,光照射对ZnTPPS的形成影响很大。光-极谱试验表明:光电流(i_p)与浓度(c)间有以下的关系:对Zn(NH_3)_4^(2+),i_p∝C_((Zn)(NH_3)_4)^(2+)_^(1/2),对H_2TPPS,i_p∝C_(H_2TPPS),ZnTPPS络合物还原波的i_p不明显。本文对其差异性和光电流产生的原因做了初步探讨。
In the solution of 0.4KOH+0.6mol NH_4Cl+0.1Im. mol/L (pH=9.5), the irradiation of UV-Vis light has great effects on the formation of ZnTPPS. The experimental results of photopolarography have shown that the relationship between photocurrent (i_p) and concentration (C) are: i_p∝C_(Zn)^(1/2)(NH_3)_4~2+for Zn(NH_3)_4~3+and i_p∝C_(H_2TPPS) for the third reduetive wave (P_3)of H_2TPPS, respectively, while the first reductive wave (P_1) of H_2TPPS and the wave P_c of ZnTPPS do not produce photocurrent. The differences in photoeurrents were discussed briefly.
