Abstract—Eco-adsorbent prepared from paper sludge, a
solid waste of paper industry, was studied to adsorb cadmium
ion in water. Some parameters such as mass of the adsorbent,
pH of solution, and shaking time were investigated in order to
know the adsorption ability of the adsorbent. The presence of
carboxyl and phenolic hydroxyl functional groups in this
adsorbent were important in the process of adsorption. It was
found that pH 6 to 8 of solution and 60 minutes of shaking time
was a suitable condition for this adsorbent in adsorbing
cadmium ion. Langmuir isotherm adsorption model was fit for
this adsorbent and the adsorption capacity for Cd(II) was 5.21
mg/g.
