In this study, we synthesized Bead-Shaped Silica and evaluated its performance in adsorbing the dye Rhodamine B. The

Bead-Shaped Silica (BS) was synthesized without the use of harmful substances. The BS Adsorbent was synthesized using

silica powder and the eco-friendly biopolymer sodium alginate through the Egg box junction method. It was found that by

adjusting the molar ratio of silica to alginate during the manufacturing process, the specifi c surface area and pore size could

be controlled. The BS-2.5 sample exhibited the highest surface area and adsorption capacity due to the eff ective removal of

alginate during heat treatment. The pseudo-fi rst-order adsorption kinetic constants and eff ective diff usivity of the BS material

decreased with decreasing pore size, while the adsorption capacity increased. The adsorption behavior of Rhodamine

B was modeled using Langmuir and Freundlich isotherms. Based on calculations using these models, the BS-2.5 sample,

which had the largest surface area, showed the best performance. Additionally, in continuous fl ow system experiments, the

use of BS resulted in clean water production, whereas columns with silica powder experienced structural damage and dye

leakage due to severe pressure drops.
