In this work, nanoscale absorbers, Tio2, were synthesized. This adsorbent was studied by scanning electron microscopy and field diffusion and X-ray diffraction. Subsequently, the material was effectively used to absorb Alizarinolva from aqueous solutions in the closed process and then derivative spectroscopy for accurate and repeatable measurements. The important parameters of the process, such as initial color concentration, pH, absorbance and ultrasound time, were optimized using a central composite design. The evaluation of kinetic and isotherm studies was studied in optimal experimental conditions. Several isotherms were used for experimental data, and isotherm constants were calculated for the yellow alizaron color. Among the applied models, the Long Moir isotherm model predicts the multiparticulate balance of the balance in the medium range of concentrations for the yellow alizarin color. . The fitting of empirical absorption data over time with different models such as the first and second pseudo-order, the allevic model and inter-particle representation, the suitability of the pseudo-second-order model and inter-particle representation for predicting the removal rate and their parameters for the yellow alizarot color .
