Removal of rhodamine dye from aqueous solution using white egg shell as low-cost adsorbent

The research of an inexpensive adsorbent for the adsorption of RD from its aqueous solution is the main goal of this work. Egg Shell Powdered (ESP), a cheap adsorbent, worked well for the sorption colors from its aqueous solution. This study investigates the possibility of using egg shell powder as an inexpensive adsorbent to remove rhodamine from aqueous solutions. For RD, the effects of primary concentration, sorption duration, and adsorbent quantity on dye removal were examined. An hour was allotted for equilibration. The equilibrium sorption isotherms have been studied using both the linear Freundlich and the Langmuir models.
