Removal of P-nitrophenol from aqueous solution using egg shell powder as a very low cost adsorbent

Abstract EN

This work deals the removal of p-nitrophenol (PNP) from its aqueous solutions using hens egg shell powder as a very low cost adsorbent.

Adsorption experiments carried out by varying the process parameters like contact time, effect of pH, adsorbent dose, initial concentration of adsorbate, particle size and effect of temperature on removal percentage of PNP have been studied.

The data of equilibrium adsorption were interpreted using Freundlich, Langmuir, and Temkin models.

The adsorption of PNP was best represented according to the Langmuir model
