Abstract

Adsorption studies were carried out with methylene blue onto cationic resin as an adsorbent

(Lewatit CNP – 80, weak acidic, carboxylic acid functional group, macroporous, cationic

type). Effect of methylene blue concentration, temperature, pH, resin dose and shaking rate

were investigated for calculating the adsorption capacity of resin. Also regeneration of resin

was studied for reuse capabilities. Adsorption experiment conditions was carried out 3 – 5

– 6 – 8 – 10 pH values, 10 – 25 – 50 – 75 – 100 ppm methylene blue concentration, 25 – 30

– 40 – 50 0C temperature and 150 – 200 – 250 – 300 rpm shaking rates. Removal capacity

of resin was calculated as 17 mg/g to 194 mg/g at 25 0C temperature, pH 5, in 15 minutes.

The removal efficiency increases with the higher pH values upto 99,63%. The study also

focuses on the adsorption capacity of the regenerated resin and reuse possibilities.
