Abstract
The rice husk treated by nitric acid was used as
adsorbent for removed methylene blue from solution
in batch adsorption system. The effects of amount of
adsorbent, initial methylene blue concentration and
temperature were investigated. The adsorption
isotherm, kinetics and thermodynamic data of
adsorption methylene blue were studied. It was
found that an increase initial concentration and
temperature of methylene blue boosted the
