Removing of heavy metals using peanut husk pdf

Removing of heavy metals using peanut husk pdf of kinetic experiments demonstrated that the adsorption was effective and rapid. The adsorption of heavy metals on sawdust and modified peanut husk is not an intraparticular diffusion control.

The kinetic adsorption data can be described by the second-order equation and the adsorption might be a rate-limiting control. The suitability of the adsorbent was tested by fitting the adsorption data with Langmuir and Freundlich isotherms, which gave good fits with both isotherms.

The influence of the pH of the metal ion solutions on the uptake levels of the metal ions by the different adsorbents used were carried out between pH 4 and pH 11.
