Activated Carbon From Tamarind Seed And Jackfruit Seed Prepared Via Microwave Irradiated For Dye Removal

Water sources such as rivers, lakes, groundwater and seas that located nearby to textile industries can be easily polluted if direct discharge of dye wastewater to the environment is occurred. Adsorbent such as activated carbon particularly produced from agrowaste has been found to be suitable f...

Adsorbent such as activated carbon particularly produced from agrowaste has been found to be suitable for this purpose. In this study, tamarind seed based activated carbon (TASAC) and jackfruit seed based activated carbon (JASAC) were prepared by using physiochemical activation.

The optimum conditions for TASAC were 440 W, 2.0 min and IR 0.5 while for JASAC was 440 W, 2.0 min and IR 0.6, which resulted MB removal of 70.4% and 83.2%, respectively; RBBR removal of 62.7% and 75.6%, respectively and yield of 21.8% and 22.5%, respectively.
