用包覆5，10，15，20-四(4-甲基苯基)卟啉的石英晶体吸附剂研究了铝(III)、铁(III)和铟(III)三种金属离子的络合现象。目的是为金属卟啉的制备选择合适的吸附剂。用石英晶体微天平(QCM)方法测定了4种温度(300~330℃)下四(4-甲基苯基)卟啉的平衡吸附等温线。随后，对实验数据进行了分析，以期对络合机理作出全面的解释。实验结果表明，氯化铝是适合金属卟啉应用的原料。通过物理吸附模型对实验等温线进行了理论分析。AlCl3等温线用理想气体定律建立的单层吸附模型模拟。而FeCl3等温线可用单层吸附来解释，该吸附包含侧向相互作用参数(真实气体定律)，表明所形成的铁-卟啉络合物的稳定性最低。用逐层公式解释了氯离子在InCl3双层吸附中的作用。有趣的是，对所采用的三个模型的物理化学研究表明，四(4-甲基苯基)卟啉的吸附是一个吸热过程，氯化铝(III)的吸附能最高(与卟啉形成化学键)，因此可以推荐用于工业应用。
A quartz crystal adsorbent coated with 5,10,15,20-tetrakis(4-methylphenyl) porphyrin was used to examine the complexation phenomenon of three metallic ions [aluminum(III), iron(III) and indium(III)]. The aim is to select the appropriate adsorbate for metalloporphyrin fabrication. The equilibrium adsorption isotherms of tetrakis(4-methylphenyl) porphyrin were performed at four temperatures (from 300 to 330 K) through the quartz crystal microbalance (QCM) method. Subsequently, the experimental data were analyzed in order to develop a thorough explanation of the complexation mechanisms. The experimental results indicated that the aluminum(III) chloride is the adequate material for metalloporphyrin application. Theoretical investigation was established through physics adsorption models in order to analyze the experimental isotherms. The AlCl3 isotherms were modeled via a single-layer adsorption model which is developed using the ideal gas law. Whereas, the FeCl3 isotherms were interpreted via a single-layer adsorption which includes the lateral interactions parameters (real gas law), indicating the lowest stability of the formed iron-porphyrin complex. The participation of the chloride ions in the double-layers adsorption of InCl3 was interpreted via layer by layer formulation. Interestingly, the physicochemical investigation of the three adopted models indicated that the tetrakis(4-methylphenyl) porphyrin adsorption was an endothermic process and that the aluminum(III) chloride can be recommended for an industrial application because it presents the highest adsorption energy (chemical bonds with porphyrins).
