Abstract
Egg production has been remarkably increased worldwide in the last thirty years, thereby itgenerates huge waste eggshell. Chicken waste eggshell is approximately 11% of the total eggweight and it contains calcium carbonate (CaCO3) and calcium oxide (CaO). In this work, wasteeggshell was modified by urea (UES) and used as a catalyst to degrade cationic dyes. Brilliant greenand Malachite green were efficiently degraded via optimization of initial concentration of dyes, pHof media, time of contact and amount of catalyst. The reaction followed first order kinetics. The LCMSstudy was performed to understand the catalytic degradation pathway of malachite green.Hence, the present study might be helpful for removal of selected organic dyes via valorisation ofwaste eggshell.
