The current research study determines the efficiency of groundnut shell-based biochar for biodecolorization of reactive blue (RB 19) in an aqueous solution in batch studies. The characteristics of the biochar were determined with the help of equipment such as energy dispersive system, Fourier transform infrared spectra, thermogravimetric analyzer (to conduct thermogravimetric analysis, i.e., TGA), and scanning electron micrograph. The researcher determined a few parameters namely, pH, temperature, initial dye concentration and dosage of the sorbent through a batch adsorption study. In addition to these, the researcher also used Freundlich followed by Langmuir as well as Toth models to determine the model's sorption capacity. Pseudo-first-order kinetic model, as well as pseudo second-order kinetic model, were utilized in the study to examine how dye molecules were sorbed at varying periods. The sorbent's capacity was tested through regeneration studies to identify optimal elutant, solid-to-liquid (S/L) ratio and sorption–elution cycles. With an uptake capacity of 7.99 mg/g, the researcher observed 53.27% reactive blue dye removal efficiency. [ABSTRACT FROM AUTHOR] |
