Abstract
for MB. SAC exhibited 100% removal of MB or ARS with concentrations lower than 150 ppm in 15 min. The data fitted well with the Langmuir model and pseudo-second-order model. Moreover, the reusability revealed that the SAC can be reused over 5 cycles without significant change in the removal efficiency. Overall, SAC and LAC derived from papaya plants exhibited excellent dye adsorption performance, suggesting potential for large-scale applications.
