• Chitosan beads are modified with sodium dodecyl sulfate, an anionic surfactant.
• Modification of chitosan beads are done at various concentration levels of SDS.
• Malachite green, a cationic dye is removed by SDS-modified chitosan beads.
• Adsolubilization of malachite green within modified beads is perceived.
Chitosan (CS) is a well recognized cationic polyelectrolyte, widely used as an adsorbent. However, CS hydrogel bead lacks its ability to adsorb cationic dyes because of the obvious repulsion between cationic CS and the dye of same charge. In this work CS hydrogel beads are modified by sodium dodecyl sulfate (SDS), an anionic surfactant, under various conditions to improve its efficiency for the adsorption of malachite green (MG), a cationic dye. In the first part, the complex forming ability of surfactant (at <
