What is it about?
Synthesis of activated carbon from annatto peels (APAC) through the carbonization method, chemical activation using 50% H3PO4 with an impregnation ratio of 1:5 (w/w), and physical activation at a temperature of 500 °C. After that, the APAC was applied as adsorbent for synthetic dyes like cibacet yellow and cibacet red.

Why is it important?
The limited use of annatto peels is the idea in this study, where annatto peel is used as raw material for activated carbon and is applied in the adsorption process in cibacet yellow and cibacet red textile dyes. The cibacet yellow and cibacet red was used as the sample of synthetic dyes because of its common use in the textile industry.
Perspectives
This article gives a new perspective about the utilization of activated carbon from anatto plants (Bixa orellana), especially as a dye adsorbent. I hope this article can be a breakthrough in handling environmental issues, one of which is water pollution.
