Ultrasonic Functionalized Egg Shell Powder for the Adsorption of Cationic Dye: Equilibrium and Kinetic Studies
نویسندگان
چکیده
The present research focuses on synthesizing surface-modified egg shell powders using ultrasonic modification method for the effective adsorption of malachite green dye (MG). presence functional groups and surface morphology ultrasonic-assisted powder (UAESP) was characterized Fourier transform infrared spectrophotometer (FTIR) scanning electron microscopy (SEM) analysis, respectively. A batch study performed to predict optimum conditions, results showed that maximum rate at solution pH 8.0 within interaction time 90 min, dosage 1.5 g/L MG concentration 25 mg/L, temperature 30°C. isotherm kinetics modeling system can be well described by Freundlich pseudosecond-order kinetics, monolayer capacity UAESP originated 64.58 mg/g. thermodynamic reported removal onto exothermic spontaneous. This accredited has higher efficiency, cost-effective, sustainable adsorbent hazardous dyes an industrial level.
