Abstract
The aim of this study is to determine the adsorption qualities of layered double hydroxides (LDH) for the uptake of herbicides BNOA (2-Naphthoxyacetic acid), which were assessed under laboratory provision with specific regard for the impact of interlayer charge and original interlayer anion. The final objective is the utilization of LDHs, recyclable adsorbents from the modification of the LDH materials and diverse catalyst for the treatment of contaminated waste waters. The Mg-Al LDH is anionic clay with the ability to expel anions from solutions by improving its layered structure. The mixed Mg-Al oxide established from the calcination of Mg-AI LDH is a good sorbent for natural anions. The intention of this work is to study the capacity of calcined Mg-Al LDH for the removal of herbicide 2,Naphthoxyacetic acid from aqueous solutions and additionally to examine the impact of pH on the recovery process. The research done for this thesis was based on the kinetics of the rejuvenation process of LDH and the kinetics of sorption isotherms of anions on the surface of LDH.
