Abstract

Adsorption of dyes as a remediation technique for dye-loaded wastewater remains an area of interest. On the other hand, adsorption using bio-derived, renewable sorbent materials can be seen as environmentally friendly, on the other hand adsorption can provide us with a trouble-free, commercially cheap operation. This main objective of this thesis is adsorption of the dyes Crystal violet (CV) and Nile Blue (NB) on activated carbon derived from date palm leaf wastes. For this purpose, activated carbon was prepared via chemical treatment of palm leaf wastes with sulfuric acid (H2SO4), phosphoric acid (H3PO4), and nitric acid (HNO3), respectively, with subsequent carbonization through thermal treatment. Dye adsorption studies with this activated carbon were carried out under different conditions, and the influence of different parameters such as temperature, time, Ph, dye concentration, dose and particular size of activated carbon (AC) was investigated in batch experiments. Furthermore, dynamic sorption experiments were performed successively. The present study found AC from date palm leaves to be a promising low cost adsorption to remove CV and NB from aqueous solutions.
