دراسة امتزاز صبغة الكونغو الحمراء على الفحم المنشط

الملخص EN

The research included studying the adsorption of congo red dye on the surface of activated carbon, where a UV-vis spectrometer was used to determine the dye concentration after adsorption.

The results showed that the adsorption isotherm corresponded with S type curves according to Giles classifications.

The comparison of correlation coefficients (R2) of the linearized form of both Freundlich and Langmuir equations indicates that the Freundlich model markedly described the adsorption of congo red on activated carbon, and the adsorption ratio increases with increasing the adsorbent dosage and with increasing the temperature, and that the adsorption process is exothermic and it occurred spontaneously.
