The optical detection of thioacetamide was investigated using a metalated porphyrin, Mn(III)-5,10,15,20-tetrakis-(3,4-dimethoxyphenyl)-21H,23H-porphyrin chloride (Mn-3,4-diMeOPP), gold colloid solution (AuNPs), and complex formed between them (Mn-3,4-diMeOPP-AuNPs) in order to select the most sensitive material achieve complementarity methods. Mn-3,4-diMeOPP, AuNPs, their were synthesized characterized by means UV-Vis, FT-IR spectrometry, AFM investigations. It could be concluded that Mn-3,4-diMeOPP detect/quantify (TAA) range 3.13 × 10-8 M-7.67 10-7 M linear fashion, with 99.85% confidence coefficient. colloidal particles alone detect TAA an extremely narrow concentration domain 2-9.8 M, slightly complementary Mn-3,4-diMeOPP. proved able quantify trace concentrations 1.99 M-1.76 polynomial method being more difficult. A potential mechanism for based on is discussed computational modeling. distorted porphyrin conformation its electronic configuration favor generation grid electrostatic interactions TAA.
