Abstract
The present thesis entitled “Reuse the activated agricultural wastes
(Sugarcane Bagasse Ash) to remove some basic and acidic dyes from
aqueous solution by using phosphoric acid” contains (118) pages,
(122) References, (8) Tables and (77) Figures, and comprises of four
chapters:
Chapter I is concerned with pollution, dyes and their hazardous effect,
common techniques for removal of dyes and the previous studies made
on the removal of Crystal violet and Methyl orange by using adsorption
technique.
Chapter II contained the preparation of adsorbents by the chemical
modification of sugarcane bagasse ash adsorbent by a composite of
bentonite and polyurethane then activated by using phosphoric acid. The
adsorbent was characterized using Brunauer–Emmett–Teller method
(SBET), Scanning Electron Microscopy (SEM), Fourier Transform
Infrared Spectroscopy (FT-IR), X-Ray Diffraction (XRD), Point of Zero
Charge pH(PZC), bulk density, moisture content, ash content, volatile
matter and carbon yield. Experimental part for using SCBBPU and SCBB
as adsorbents for the removal of Crystal violet and Methyl orange from
aqueous solutions through the batch adsorption process
