原始语种摘要: Abstract(#br)The present study describes the detailed investigations of the solubilization of thiophene derivatives i.e. 5-(2-(benzyloxy) phenyl) thiophene-2-sulfonamide (BPTS) and 5-bromothiophene-2-sulfonamide (BTS) by micellar solution of anionic surfactant, Sodium dodecyl sulphate (SDS). The interaction of SDS in the solution containing aforementioned compounds was investigated by electrical conductivity and UV–vis spectroscopy. The data of electrical conductivity was used to calculate thermodynamic parameters like free energy (ΔG m ), enthalpy (ΔH m ) and entropy (ΔS m ) of micellization of SDS in the presence of thiophenes, whereas UV–vis spectroscopy was used to calculate the extent of solubilization in term of partition coefficient (K x ), free energy of partition (ΔG p ), binding...
