This study represents the removal of harmful dye
substances from wastewaters by using a waste and cheap biosorbent. For this aim, peanut shell was used as a biosorbent
for the removal of methylene blue and acid red 88 dyes. The effects biosorbent amount,
initial dye concentration, pH, temperature, contact time and dye type on
biosorption were studied. In the study, the highest removal of acid red 88 was
found as 88% using dye solution of 200 ppm with 5.0 grams of peanut shell at
contact time of 300 minutes. The highest removal of methylene blue was determined
as 99% using dye solution of 200 ppm with 4.0 grams of peanut shell at contact
time of 60 minutes. As a result of dye type, methylene blue which has a linear
geometric structure has demonsrated a high removal than acid red 88.
Biosorption isotherms for both dyes were found more consistent with the
Langmuir model according to Freundlich model.
