Investigation of the Chitosan Immobilized Eggshell for the Biosorption of Brillant Blue R Dye

Abstract

S ince dyes are colored compounds, they are one of the most easily recognizable contaminants in the environment. These compounds are found in many areas of the industry like: textile, color photography, cosmetics, paper, printing, plastic, food, etc. for product coloring (1-4). The fact that dye is poisonous reveals how important it is to remove dye from wastewater in terms of ecology (5, 6).The discharge of dyes is carried out using a variety of methods such as biological degradation, membrane technologies, coagulation-flocculation, electrochemical techniques, advanced oxidation, chemical flocculation and precipitation, electrochemical, membrane filtration, ion exchange, aerobic, anaerobic and biosorption methods(7-9). Apart from these methods, the biosorption technique has been very popular in recent years in terms of chromatographic processes (10, 11).For the first time, the adsorption method was introduced by Scheele in 1773 and Abbe Fontana in 1777 (12). Adsorption can be defined as the increase of surface concentration by attaching atoms, ions, and molecules to a solid surface (13). Several different natural and waste adsorbents have been investigated to remove
