Study the thermal dynamics of calcon dye adsorption on surfaces of natural materials

الملخص EN

Theresearch includes a study of the thermal dynamics of calcon dyeadsorption, by using ultra-violet-visible spectroscopy technique ,temperature has been investigated at (298-328k), the results obtained indicate that the adsorption of calcon dye, increase with increase of temperature, in the other words, the adsorption process is endothermic and h is positive.

the effect of the acid function was also studied, the results obtained were follows according to the sequence :pH: 7 > 9 > 5.
