Removal of Zn (II) and Cu (II) Ions from Aqueous Solution by Dried Prosopis JULIFLORA

Abstract

The use of cheap and ecofriendly adsorbents was been studied to find an alternative substitution of activated carbon for the removal heavy metals from wastewater. Prosopis juliflora is an invasive weed which posing a great environmental threat to other flora all over the world. In this study, the influence of physico-chemical key parameters such as the solution pH, the contact time, adsorbent dose, etc. The obtained experimental results have been fitted according to the two known adsorption models of Langmuir and Freundlich. The adsorption best fits the Langumir adsorption isotherm, which shows homogenous nature of adsorption. Prosopis juliflora can be a novel adsorbent according to results obtained in this study on the adsorbent dried prosofis juliflora. It is recommendable to use this weed as an adsorbent as it is obvious of solving two problems with one cure in the environment.
