Algoritmo de Matlab® para calcular isotermas de adsorción de Langmuir de ácidos carboxílicos sobre carbón activado o Amberlite IRA 67 como adsorbentes sólidos.

An algorithm is written to predict the adsorption behavior by obtaining Langmuir adsorption isotherm parameters from experimental data found in the scientific literature, which will be adjusted by means of a linear regression executed in Matlab®. This algorithm is applied to compare the adsorption of formic and acetic acid on activated carbon and Amberlite IRA-67 defining the Langmuir adsorption isotherms. Activated carbon is a commonly used industrial adsorbent, Amberlite IRA-67 resin is a weakly basic polyacrylic resin with a tertiary amine functional group. The result of this comparison shows that activated carbon is more effective than Amberlite IRA-67 resin when adsorbing the carboxylic acids studied.
