用三波长分光光度法在pH=5.0,μ=0.2(NaNO_3)和25℃条件下,按改进的Sanchez法测定了Cu(Ⅱ)-碘化四-(4-三甲胺苯基)卟啉配合物的稳定常数为7.73×10~7,组成比为1:1。
The Cu (Ⅱ) -iodinated tetrakis (4-trimethylaminophenyl) porphyrin complex was determined by the improved Sanchez method under the conditions of pH = 5.0, μ = 0.2 (NaNO_3) and 25 ℃ by using three-wavelength spectrophotometry The stability constant of the material is 7.73 × 10 ~ 7, the composition ratio is 1: 1.
