Biosorption of Procion Magenta and Black Azabache textile dyes using banana and carrot peel waste: a comparative analysis of pure and blended systems.

PubMed · 2026-04-23

Banana and carrot peels — kitchen waste most people throw away — can effectively remove toxic textile dyes from wastewater, offering a cheap, plant-based alternative to industrial water treatment chemicals.

1

Best dye removal occurred at a concentration of 100 mg/L, suggesting an optimal loading point for these biosorbents

2

Both banana peel and carrot peel waste were effective at adsorbing Procion MX Magenta (a pure dye) and Black Azabache (a blended multi-dye formulation)

3

This is the first comparative study evaluating pure vs. blended dye systems using these two agricultural waste biosorbents side by side
