The complexation of sodium molybdate with para-sulfonatocalix [4] arene was studied in the temperature range from 20 to 40 °C and pH = 5.8 by spectroscopic method in water solution. The stability constants of complexes were calculated by the multiwavelength analysis of spectral data using SQUAD program. The equilibrium constant, spectroscopic data, molar absorptivities and concentrations of all species were adequately optimized by program when the chemical model with 1:1 stoichiometry was considered in the calculation. The extracted values of molar absorptivities and concentration- profile of the formed complex were reported. The logarithms of the stability constants of complexes were calculated to be 3.672, 3.143, 2.986, 2.555, and 2.333 at20, 25, 30, 35and 40 °C respectively
