Development of Eco-adsorbent Based on Solid Waste of Paper Industry to Adsorb Cadmium Ion in Water

Eko Siswoyo and Shunitz Tanaka
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.

Index Terms—Cadmium, Eco-adsorbent, Langmuir, paper sludge carbon.
