GURUPI ISOTHERMS PLOT (GIP): UMA FERRAMENTA COM INTERFACE GRáFICA INTUITIVA E GRATUITA COMO ALTERNATIVA PARA O CáLCULO DE PARâMETROS DE ISOTERMA DE ADSORçãO

GURUPI ISOTHERMS PLOT (GIP): A TOOL WITH INTUITIVE AND FREE GRAPHIC INTERFACE AS AN ALTERNATIVE FOR THE CALCULATION OF ADSORPTION ISOTHERMA PARAMETERS. Gurupi Isotherms Plot (GIP) is a new software and has been developed to facilitate the study of absorptive processes. The adsorption isotherm parameters are determined by the GIP in a non-linearized way, and the current version is implemented to determine the parameters of Langmuir, Freundlich, Dubinin-Radushkevich, coefficient of determination (R22 Poonkuzhali, K.; Rajeswari, V.; Saravanakumar, T.; Viswanathamurthi, P.; Park, S.M.; Govarthanan, M.; Sathishkumar, P.; J. Hazard. Mater. 2014, 272, 89.) and average relative error (ARE). In order to facilitate the access and use of the program, a friendly graphical interface has been developed with a response time in seconds. It should also be noted that is a free software. The program was tested with different sets of absorptive data and showed an excellent correlation with the literature data proving its performance.
