Removal of crystal violet and acid green dye in aqueous solution using banana plant-derived sorbents; [Penyingkiran pewarna crystal violet dan acid green dalam larutan akues menggunakan penjerap berasaskan pokok pisang]

In this study, the sorption of crystal violet (CV) and acid green (AG) dyes from aqueous solution was performed using banana plant-derived sorbents. Kinetics for both dyes showed that percentage removal increased with a contact time until equilibrium, where it stays almost constant. For CV dye, the...

In this study, the sorption of crystal violet (CV) and acid green (AG) dyes from aqueous solution was performed using banana plant-derived sorbents. Kinetics for both dyes showed that percentage removal increased with a contact time until equilibrium, where it stays almost constant. For CV dye, the percentage removal was above 90% at equilibrium. On the other hand, the percentage removal of AG dye was between 44-54% for the three sorbents. To study the effect of sorbent dose, the dose of the sorbents used was varied from 1 to 100 g/L. From the results, it was observed that an increase in sorbent dose would result in an increase of percentage removal of both dyes. However, for CV dye, the percentage removal became constant after 10 g/L. The effect of pH was also determined for both dye removal, where it was found that CV dye was unaffected by pH change. However, the AG dye can be removed more in highly acidic conditions. © 2018, Malaysian Society of Analytical Sciences. All rights reserved.
